High-Voltage Leak Detection Study

Container closure testing (CCIT) has many different method variations ranging from pharma packaging to medications by themselves. Companies implements these tests for the health and safety of the public. A study was recently conducted by Nadeen Bahnam, a researcher at Uppsala University. The aim was to explore High Voltage Leak Detection (HVLD) viability as a CCIT method concerning FDA requirements. Researcher Bahnam achieved this by comparing HVLD to other known CCIT processes. The purpose of CCIT is to make sure that no contaminants of any kind, such as microorganisms, find their way into sterile products and render them useless. The study outlines CCIT methods that fall under destructive and probabilistic or nondestructive and deterministic. Deterministic methods remove randomness and provide quantitative data points assuming conditions are kept constant. By contrast, probabilistic tests include a degree of randomness, requiring a large sample size to draw conclusions. Each method has advantages and disadvantages that determine its application. The method chosen must detect the minimum-sized leak allowed for a given product.

HVLD works by passing a current through a container, and if a leak is present, the returning voltage will be higher based on the size of the leakage. The method gives fast results and is flexible given the container is nonconductive and the packaging contains a conductive liquid. Researcher Bahnam chose Lenox Laser as the supplier of reliable leaks to evaluate HVLD because of our small-hole drilling capabilities. We were selected over other suppliers because of our ability to provide certification and produce holes of 5μm or less.

Lenox laser was privileged and honored to provide test packaging for this study. We are proud to help further research in such a vital field as CCIT.

SpaceX has had quite a rich history and has come a long way since its maiden launch of the Falcon 1 rocket on September 28, 2008. Falcon 1 became the first privately funded liquid-fueled rocket to successfully reach orbit. In the following year, they became the first privately funded company to launch a satellite in orbit. Little did they know at the time, this would lead to something massive like the Starlink program. This program aims to launch a network of satellites designed to provide fast Internet speeds to areas without access. The Starlink program could also be used for military and government applications as well as other telecommunications.

In 2014, the now-famous Dragon crew was unveiled with its first successful launch six years later in 2020. The mission was successful in sending two astronauts into space to study aboard the International Space Station. This was particularly impressive given the challenges faced that year. Several Dragon crew missions are in the works for the near future.

SpaceX’s next challenging endeavor is the launch of its Starship program, which as of now, is tentatively set to launch in July of this year. Starship rockets would be reusable for long-duration cargo missions and passenger flights. The first obstacles include ensuring the program follows all government regulations from NASA, FAA, and other branches. Filings with the FCC began on May 13, 2021. If successful, SpaceX hopes to have a fully integrated continuous working network that would work together with Starlink.

Lenox Laser wishes SpaceX and all involved the greatest of success in this endeavor.

NASA Announces Two Missions to Venus

NASA has announced to future missions that will hopefully shed more light on the mystery planet that is Venus. Venus has characteristics almost identical to Earth. However, currently, scientists know so little about the planet itself. When comparing Venus to Earth, both worlds have complex weather systems, size, atmospheric composition, and density. Both planets are near the sun, with Venus being thirty percent closer to it than Earth. Scientist also refer to Venus as Earth’s sister planet because of its volcanic activity, plateaus, and water availability. In order to help with lack of knowledge about the fiery planet, NASA has planned two missions codenamed DAVINCI+ and VERITAS to study the planet further. The mission’s primary goal is to design a detailed 3-D model of Venus to better understand the planet’s environmental makeup, features, activity atmosphere, and more.

With the excitement building of new exploration and understanding also comes new groundbreaking technology to aid discovery. Mission VERITAS will use technologies like an atomic clock in deep space with great precision that will allow spacecraft to traverse and approach the planet. Once this 3-D model of Venus is created, scientists believe that things like real-time evaluations of the planet will presumably be achievable. With $500 million given for the missions, NASA plans a launch date anywhere between 2028 and 2030. While this undertaking will undoubtedly be an immense challenge, the information that NASA could unlock with these missions could rewrite our understanding of Venus.

Lenox Laser’s High-Power Aperture Mount

When working with optical apertures, it is essential to maintain the utility and longevity of those tools. Spatial filtering of a high-energy laser beam is a non-trivial problem when the energy density of the focused beam approaches the ablation threshold of the optical aperture material. Materials with a high ablation threshold have very low thermal conductivity; thus, depending upon the repetition rate of laser pulses can become subject to melting proceeded by aperture damage.

The Lenox Laser Corporation has developed the HEA-100C high-energy aperture mount that uses the combination of reflecting and heat-dissipating parts to reduce the energy density that reaches the aperture by a few orders of magnitude. Our team worked meticulously and thoroughly to ensure that not only the utmost quality was given to the product but also a long-lasting lifespan. This process includes rigorous testing and configuration of different scenarios that meet our impeccable standard of excellence. This method significantly extends the lifetime of the optical aperture. Our engineering team selected the HEA-100C dimensions to fit most optomechanical mounts designed for one-inch mirrors or lenses provided by leading manufacturers; namely CVI-Melles Griot, Newport, New Focus, Thorlabs, Edmund Optics, etcetera. Our mounts can mount any aperture. When done so, they become an integrative part of the existing optical layout or device. The mounts also do not require any additional adaptors.

Our quality, high-powered apertures can also complement our mounts. The apertures — made in various materials — are used for things like Q switching and laser balance and flow. If you would like to know more about our apertures, check out our vast product range.

As always, Lenox Laser thanks our readers for taking the time to read about our exciting endeavors every week. Please contact us at any time, and we will happily assist you.

Dr. Charles H. Townes Speech – Revisited

Dr. Townes and the first maser

The human mind has given us some of the most outstanding achievements throughout history. As our thirst for knowledge and understanding continues to grow, new ideas are born. One of those great minds was Charles Hard Townes, the inventor of the maser, the precursor to the laser. Dr. Townes wasn’t just an inventor but also a patriot serving his country in war and a brilliant university professor. During World War II, he worked under Bell Labs as a radar technician in the hope that his expertise would turn the tables on the enemy. This effort would give birth to the shortest wavelength radar by seeing the effects of light on it. Upon returning from the Navy, he would lead a research team at Columbia University, where he and his team would study molecules.

After becoming a professor at Columbia, he and his dedicated students would design a molecule oscillator that would be endlessly argued over. From the discussion with his students, Townes and others arrived at their latest invention — the maser, Microwave Amplification by Stimulated Emission Radiation. Dr. Townes was an example that both patients and trial and error can lead to remarkable discovery and creation. In October 2010, Dr. Townes give a speech at Lenox Laser during our one of our light seminars entitled “How New Things Happen.” During the speech, he mentioned that ideas often happen by accident. Those accidents can involve a network of people. One’s patience can be rewarded in unexpected ways while still reaching your goal in the end.

Townes’s legacy and contributions to history remain greatly appreciated and never forgotten. Please visit the Industrial Institute of Optics to read or watch Dr. Townes’s speech in its entirety.

James Webb Update – Golden Mirror Test

               As the James Webb telescope launch on Halloween this year fast approaches, the project continues to make strides toward that day. From past achievements such as folding up and packing the massive tennis court size sunshield to testing the shield itself, the exciting project has made tremendous progress. The most recent milestone was the completed final testing of the telescope’s gold mirror. The mirror is precisely 6.5 m wide, and its purpose will be to reflect light back from galaxies and stars for further study on Earth. This test marks the final time the gold mirror will be checked before it is packed up and shipped off to the launch site. The tests have been conducted by Northrop Grumman, the team that is helping build James Webb. The mirror itself must precisely fold into the launch rocket without error or any form of damage. It consists of two wings folded up in an ongoing simulation conducted over the next several days. The final part of the mirror will be folded. Beryllium makes up the primary mirror in the telescope that cost $10 billion. Webb will use the received infrared light to take readings of the stars and galaxies, allowing humanity to see inside galaxies like never before. Several projects hope to be a part of James Webb in the first year of its operation as astronauts from over 40 countries have allocated time on the telescope.

               Lenox Laser had the honor of being part of the project by designing precision alignment targets for its mid-infrared instrument (MIRI). Lenox Laser was even invited to see this process firsthand when they were created. Given all of James Webb’s technology, it was designed so that no human is needed for repairs. Although if desperately needed, a piloted crew could be sent to perform repairs and come home from a short mission. James Webb will be the new premier space telescope for US outer space study if all is successful. Lenox Laser wishes the very best to all involved and extends a heartfelt thank you for allowing us to be a part of this monumental moment in history.
