Covid-19 Study Measuring Droplet Travel Distance With Laser Light

2020 has been a challenging year with the ongoing Coronavirus pandemic. The novel virus — known as SARS-CoV-2 or more colloquially Covid-19 — has shut down the globe for many months. As research on the illness continues, knowledge of the disease is rapidly evolving. For example, research suggests the virus is transmitted through coughing sneezing and even speech droplets. A study published in the Proceedings of the National Academy of Sciences, the official journal of the National Academy of Sciences, found. “Highly sensitive laser light scattering observations have revealed that loud speech can emit thousands of oral fluid droplets per second.” CDC guidelines have recommended such things as facemasks and 6 feet apart social distancing because of these findings. 

Researchers estimate that droplets can travel 16 feet when walking. As for running, droplets can spread an estimated 32 feet travel distance minus a tailwind. Certain variables in a room can also contribute to airborne spread such as temperature, humidity, open windows, and air quality. Droplets will usually vanish in a matter of 15 minutes or so. If a person competes in a track race, the other runners may still be at risk of infection because of the droplets from other runners. 

Scientists have suggested that — like the common flu — Covid-19 is something humanity may have to coexist with. With modern medicine, we have the best chance in fighting such a virus. Medical teams and staff and health care workers are working around the clock to give the world hope for a better tomorrow. Lenox Laser sends our best to everyone out there affected, and our sincere thanks to healthcare workers the tremendous efforts put forth every day. Thank you, and stay safe.

Using an Imager on a Tethered Balloon System for Observations of Boundary Layer Clouds

Clouds are such a mysterious and beautiful part of nature, but equally challenging to understand. Researchers Fabiola Ramelli, Alexander Beck, Jan Henneberger, and Ulrike Lohmann created a weather balloon meteorology system to study the boundary layer of clouds. These are essential in helping understand the Earth’s climate. The technology used during the initial phase was deemed incapable of completing the goal of the study. With the study’s goal in jeopardy, Lenox Laser provided small holes in a holoBalloon.

These holoBalloons could effectively measure the makeup of the cloud, the density shape, size, and more onto a holographic imager. The balloon can have a static and aerodynamic lift. The balloon inside is made up of the battery, a global positioning system, temperature and humidity sensor, and a 3-D sonic anemometer. Those items placed inside the balloon were used to simulate a resistance test when the holoBalloon was tethered to the ground via a winch. 10 µm diamond pinholes — drilled by Lenox Laser — provided a light source for the balloon’s optical systems. The laser beam used for the drilling was around the width of 40 mm. The hope for this balloon is to measure cloud factors such as heat, density, temperature, and wind speed. This is a massive leap forward in determining dangerous weather elements and delivering the results to the public and Lenox Laser was honored to have been a part of it.

James Webb Telescope Launch Update

The James Webb Space Telescope is on quite a state of evolutions in its journey to launch, and that journey is not over. Initially, the launch date for the Telescope was in 2007, but now the estimated launch date is set for some time in March of 2021. The original 2007 launch had the project at the cost of $500 million. Due to several delays with the global coronavirus pandemic, the project now has an estimated cost of $10 billion. Wrong cleaning solvents and fasteners misused on the Telescope mirrors caused the latest delay in the launch. The journeys of space entail massive planning, and with that comes unforeseen changes. However, if history has taught anything, it is that changes like these can lead to great achievements. 

For all its adjustments and changes, James Webb had a successful testing and full deployment of its mirror systems in early June 2020. Despite setbacks, NASA will not decrease the funding budget for this massive project. The James Webb Space Telescope has been in the works for nearly three decades. With enormous effort behind it, a new date will hopefully come soon for the launch. For more information about James Webb and other NASA ventures that involved Lenox Laser, visit our blog. We will give updates on this ongoing venture when possible and send best wishes to all included in the project. 

NIH Study and Lenox Laser Blog

The mind is one of the most potent tools that humanity has at its disposal. From thinking up creative ideas to decorate the house from the genius of the late Stephen Hawking to the theories of Albert Einstein, the brain has endless potential. As the intrigue around the brain has grown, scientists have continued gathering information about such a unique body part with the help of technology. During a National Institute of Health five-year brain study, Lenox Laser helped create microprobes to improve brain protein delivery.

This study included such prestigious places like New York University and RayBiotech Inc. offered their services to help in this monumental and potentially groundbreaking venture. Lenox Laser provided laser-perforated and push-pull perfused microprobes. These microprobes would be implemented primarily in the brains of rats combined with polypeptide hormones. The goal in finding these proteins would be so that scientists can break down the gene makeup such debilitating diseases as Epilepsy, Alzheimer’s, and other forms of Dementia. The other goal was to improve the efficiency and speed of delivering the proteins through microprobes. It is hoped still to this day that further studies will give us more information for fighting these diseases. This could also lead to diagnoses of unknown brain issues and other unforeseen ailments. We were honored to take part in such a notable study.

We would like to acknowledge and thank all who took part in this grand effort. Lenox Laser is in a constant state of amazement at the work and breakthroughs that the world makes every day in medicine. To read about the study, please go here.

The SpaceX Dragon Crew – An Overlook

On May 31, 2020, NASA made history with the SpaceX program launching two American astronauts into space on a privately-owned spaceship. Doug Hurley and Bob Behnken were the history-making team on a planned six-week mission to the international space station. The world will be forever in awe at the Dragon crews’ achievements as the mission is a true milestone in history.

Astronaut Doug Hurley has been in the astronaut program an astounding 20 years joining in the year 2000. Hurley, who proudly served in the US Marine Corps for more than 24 years, accumulated over 5,500 hours of flight time over his career. Hurley was already an operations officer upon being selected by NASA for the astronaut program. 

Along with Doug Hurley is astronaut Bob Behnken, who also joined the program in 2000. Behnken was a Colonel in the U.S. Air Force, where he helped manage and develop new weapon systems. He has over 1,500 hours of flight experience, a Bachelor of Science degree in physics and mechanical engineering from Washington University, and a Master of Science in mechanical engineering from the California Institute of Technology. 

With these monumental achievements of these two extraordinary and brave men, it will be incredible for the entire world to witness the outcome of Dragon’s discoveries. Most remarkable of all, the planet will experience it together. Also, a new first for any NASA launch, during the broadcast around the world, audiences could see two different camera angles – one inside the cockpit of the shuttle and one outside. We at Lenox Laser wish the mission and the astronauts all the best of luck and safe return home. 

SpaceX Crew Dragon Launch Update

With storms raging across Florida’s “Space Coast,” the SpaceX decided against the launch of its Crew Dragon shuttle on Wednesday, May 27th, 2020. SpaceX has stated that there will be another chance to launch the spacecraft on Saturday, May 30th, 2020, if the weather permits it. However, this seems to also be in doubt with weather forecasts – until the time of writing – predict more stormy weather to hang over the site of the launch on Saturday. Should Saturday also turn out to be not an optimal day for the launch, SpaceX will push it to the next day – Sunday, May 31st, 2020. This news has hit the two astronauts of the Crew Dragon space shuttle the hardest.

Astronauts Douglas Hurley and Robert Behnken have been training for the past four years in anticipation of the world’s first privately funded spaceship. As if it were routine, they put on their suits and went to the launch pad. After talking with their respective families and buckling in for the launch, they awaited the go-ahead from command to begin the launch sequence. Meanwhile, SpaceX leaders were anticipating the final call from the forecasters, who had remained optimistic all day, despite the bad weather. Ten minutes before launch, however, the mission managers overseeing the launch received word that weather conditions would not improve and, therefore, had to cancel the launch. Both NASA Administrator Jim Bridenstine and SpaceX founder Elon Musk both stated that mission safety was of higher priority than the historical significance of the mission.

We at Lenox Laser support the safety of the mission’s crew, and we are looking forward to the rescheduled launch on Saturday. We are excited by the possibility of the world’s first privately owned and operated spaceship and wish the best for both the crew and the supporters of the mission.

SpaceX Demo-2 Launch Update

On May 27, 2020, SpaceX and NASA are planning to launch the SpaceX Demo-2 mission for its own Crew Dragon spacecraft. It will be the first American astronaut mission for SpaceX. SpaceX is founded in 2002 by Tesla creator, Elon Musk. His hopes are to use the program to have human colonization of Mars in the future. Two astronauts will pilot the mission — Doug Hurley and Bob Behnken — which, if successful, will last three months. The cost of this mission is near a staggering $8 billion venture, and it is hoped that this mission marks the first time that SpaceX has ever put a human in space.

The crew will travel to the International Space Station, where they are expected to stay for more than 100 days. As this is also NASA’s first shuttle mission since 2011, the readiness review for the journey will be given today if all goes to plan. SpaceX has had significant success in the past with the launch of 60 satellites for its Starlink program. The mission’s astronauts have entered a strict final quarantine before launch, and they are in final preparations for the ambitious May 27 launch. One of the mission’s most significant measures is to ensure that no one involved has tested positive for SARS-CoV-2.

With this groundbreaking mission, it is hoped that SpaceX can hit the ground running with an extensive, constantly evolving list of innovations for not only space travel, but the world. It is certainly true today that technology knows no bounds. We at Lenox Laser would like to wish SpaceX the absolute best of luck with this endeavor. The world cheers you on.

Lenox Earns the Contractor Team Spirit Award

The NASA space missions have been an unforgettable and permanent part of American history. A recent example is the STEREO mission; the objective of the STEREO mission was to study the sun’s many particles, compositions, and solar winds. Many photos were taken since the mission launch from Cape Canaveral on October 26, 2006. It lasted 12 years despite being planned for only two. The images taken from the mission could then be viewed as a 3-D image. Lenox Laser had the prestigious honor to design some of the instruments that would help guide STEREOS imaging systems.

For our part, Lenox Laser worked on the NASA/GFCF focus test for the EUV imager that would be put on board the STEREO. NASA’s Instrument Systems and Technology Division, the Contractor Team Spirit Award – was presented to Lenox Laser for our hard work. Without this and all other contributions to the STEREO, the images would not have been what they are today. The honor was beyond humbling for us. We hope to continue to watch NASA’s innovations in their awe-inspiring glory.

A 2004 Laser Study

The laser is the perfect modern-day, precise cutting tool. It is helpful in the production of many products
today – products that range from big to small. The exactness of a laser is its biggest asset. Beyond just helping
the creation of new material, however, the laser can also be used to remove unwanted content from any
surface. This process is known as laser ablation, and it has been pioneered and innovated by Lenox Laser over
our 35 years of service.

Challenging the threshold of what the laser can drill is always is what we do at Lenox Laser. We handle
everything from laser drilling holes as small as 0.5 µm to using a scanning electron microscope or SEM, which
produces images by scanning a surface. Lenox Laser took part in a project in 2004 to help develop the best
method for creating holes via standard thickness substances or more substantial areas. Published in the
Journal of Semiconductor Technology and Science, Lenox Laser was privileged to be a part of this innovative
experiment. The publication can be read here. In this study, the goal was to test laser ablation against the
typical procedure of dry plasma etching in making holes that could work for the designing of transistors, for
example. The conclusion was that not only was laser ablation faster but also did the job with less
contamination in the product.

This experiment was another achievement, and Lenox Laser was proud to take part in and hope that future
contributions such as this continue to change and evolve to exciting new heights and prospects. As we look
back on this, we send our thanks to all that had been helping to make this possible. Here is to many more
breakthroughs in the future. As always, to learn more about our laser drilling processes; and for our services,

CCIT Vacuum Decay Leak Study

In the pharmaceutical industry, products must stay sterile as they are transported. One of the critical steps of
Container Closure Integrity Testing (CCIT) is performing leak testing. A study – by Jayshree Patel et al. – tested
their method to see if it would be faster and more effective. The experiment designed the test as an in-progress package integrity test from manufacturing and tests for stability. This would allow manufactures to
check for any types of defective packaging before mass shipment was approved. The time it takes to test
packages is surprisingly fast at less than one minute per container. The package defects tested can range from
glass vials with testing of the glass walls, to ceiling surface defects. When it came to the hole testing and
drilling of the holes, Lenox Laser was there to help.

When asked by the researchers for the study, Lenox Laser provided hole creation and size certification for the
tests performed. We were able to drill holes the size of or equal to 5 µm in diameter – the precise size needed
for the study. The validation tests used were successfully able to detect the dimensions of the holes in glass
vials. The validation tests were performed at White House Analytical Laboratories in White House, New Jersey.
CCIT is a significant process to what Lenox Laser does, and we take pride in helping any way that we can to
ensure the safety of pharmaceutical packaging.

Lenox Laser can provide many laser drilling needs for different materials, including plastics, nickel, steel, etc.
We can drill any size hole big or small to exact size with precision accuracy if you’d like to learn more about
Lenox Laser services, please visit Lenox Laser Services and our CCIT page. It was a pleasure to assist the
Parental Drug Association in this exciting endeavor of testing. We can’t wait to see the positive effect on the
industry because of this study.
