What is Pinhole Photography?

Pinhole photography is photography using a pinhole or aperture instead of a lens. These apertures are tiny holes used to focus light and capture the image. Using a camera in this way creates a light-proof box between the aperture and sensor allowing the pinhole photographer to capture the subject of the photo. Once light passes through the single point on the aperture it is inverted and captured by the film, sensor, or screen. A unique property of pinhole photography is when capturing an image there is no defined focus within the field of view. This along with controlling the amount of light allowed into their photographs gives pinhole photographers a unique perspective on the art of photography.

The history dates back to 330 BC with Aristotle questioning the ability to make a circular image when shining through a square hole marking the first reference to the optic laws that make pinhole cameras possible. In 1000 AD Alhazen (Ibn Al-Haytham) invented the first pinhole camera. He was the authority on optics during his time in the Middle Ages. To learn more about the history of pinhole photography, cameras, and photography as a whole, please visit the International Institute of Optics and the 3rd Annual Light Seminar.

Lenox Laser’s Joe d’Entremont and Josh Anderson took to experimenting with pinhole photography using pinhole caps from Daystar Laser. Daystar Laser’s pinhole caps allow for pinhole photography using a digital camera. Below is a selection of photos from the experiment.

Young’s Double Slit

We don’t often think about fascinating characteristics of light. Famous physicist Thomas Young dared to create an experiment to understand the true power of light. Born in June 1773, Thomas Young was known as an English polymath and the Renaissance man of his time. In his lifetime he would do astounding things in the field of vision, solid mechanics, energy physiology, and Egyptology to name a few. World renowned scientists Albert Einstein praised his work. In 1803 Young came up with an experiment he dubbed the young double slit.

The experiment was based on the classic proof of the wave theory of light. While Young’s original experiment used sunlight and calculated the average wavelength to be 550nm, today using monochromatic and coherent light we can calculate wavelength using the following formula:

nλ = xd/L

λ is the wavelength of the light
d is the separation of the slits
n is the order of maximum observed ( for first order n=1)
x is the distance between the bands of light and the central maximum
L is the distance from the slits to the screen center point

Young’s double slits are manufactured by Lenox Laser’s proprietary technology giving a very sharp edge to every slit that makes the geometries and areas of each slit equal (within specifications). This guarantees a very high contrast of diffraction patterns and low flux variations through each of the slits, due to good metrology and methodology.

Science Fair Competition of Maryland

Lenox Laser is a company that prides itself on a wealth of growing ideas and new exciting concepts. With this in mind, Lenox Laser began hosting the Science Fair Competition of Maryland. The fair allows children to spend the summer with Lenox Laser during a variety of different activities of great educational value. The idea of such events began as early as December 2001 at the Parkville High School robotics competition.

The very first Science Fair Competition of Maryland would be in March 2003. The fair was open to all children and teenagers with a certain scientific curiosity. Gilbert Smith of the NASA Goddard Space Center would provide the children in attendance that day with an educational presentation. The fair not only covers science, but things like mathematics, robotics, chemistry, photography, optics and astronomy and of course, lasers.

The 2016 science fair had kids ages 11 to 16 group studying innovation, creation, and reverse engineering. Motors from lawn mowers, RC cars and weed whackers were used to demonstrate the many ways to create something new. Lenox Laser’s interchangeable E-Blox technology, which can be used to build practically anything anyone could imagine, was also brought to the table, as well as 3-D printing technology. The printer was used by the students as they wrote out their names with it. A parade was also held that year to celebrate all that had been achieved and created allowing the kids to show off what was made.

The science fair is becoming a staple in the Lenox laser community and has gained a lot of wonderful support and once-in-a-lifetime experiences for all involved. Lenox Laser’s goal is to host another science fair in the summer of 2020.

Lenox Laser’s Third Annual Light Seminar

With the success of two light seminars in the history books, Lenox Laser hosted the 3rd Annual Light Seminar on October 4th 2012. This seminar focused on photography. More specifically, the seminar covered the overall history of photography and its different types be that, digital, pinhole photography, the first digital camera and even the evolution of Kodak with companies like Apple.

The seminar included many guest and keynote speakers such as Steven J Sasson, the inventor of the digital camera at Eastman Kodak in 1975. Mr. Sasson’s notable accolades include the 2001 Eastman innovation award, 2009 honorary Dr. of science from the University of Rochester, and an induction in the inventor’s Hall of Fame in 2011 along with numerous others. His speech for the night was called “Disruptive Innovation This Story of the First Digital Camera” in which he would mention that Kodak D5000(ECAM), capable at the time of producing 1.3-million-megapixel image, was introduced during a trade show in 1989. In an amazing partnership with Apple, Kodak was able to bring the public the Apple Quick Take Consumer camera in 1994. In speaking about the Apple partnership, Mr. Sasson’s speech states: “in 1984, Apple came to us at Kodak. Their computers were more imaging friendly than Intel at the time. It had to do with the architecture of the CPUs they were using at the time. They told us if we could build a digital camera it would emigrate on rent for their computers and both parties would sell more.”

Next up would be Mr. Dirk Fletcher discussing his fascination with pinhole photography and camera lenses as well as well as the DSLR camera. Pinhole photography is a camera without a conventional lens. Instead it uses a small aperture creating a light proof box light from which the scene passes through. This is also known as the camera obscura affect. The last two speakers of the night were black and white pinhole photographer Richard A Johnson discussing his pinhole photography fascination as well as travels and photographer Paul Johnson with the demonstration of certain lighting effects in photos. Mr. Johnson also discussed his belief in the importance of preserving memories with photography.

A beautiful photograph can capture memories to last a lifetime and be frozen in time forever, much like the memories of these wonderful light seminars hosted by Lenox Laser, cheers to photo memories new and old and many yet to come.

Lenox Laser’s Second Annual Light Seminar

Lenox Laser has an amazing legacy that we hope will continue to grow for many years to come. Adding to that legacy is the fact that on October 4, 2011, Lenox Laser hosted its second annual light seminar celebrating Lenox Laser’s 30th anniversary.

The seminar would feature some amazing presentations with a renowned and respected keynote speaker, Dr. John C Mather. Dr. Mather discussed the famed James Webb Space Telescope and the Big Bang theory. Dr. Mather served as the Senior Project Scientist on the James Webb Space Telescope. He was the recipient of the 2006 Nobel Prize in physics for the discovery of the blackbody form and anisotropy of the cosmic microwave background radiation. Dr. Mather’s speech was called “History of The Universe in a Nutshell from the Big Bang to Life to the End of Time.” An excerpt from the speech states: “To begin at the beginning-the universe is been expanding for a very long time. We now think that is been doing this for 13.7 billion years.” At the speech’s conclusion, Lenox Laser President Joe d’Entremont presented Dr. Mather with an art piece by Gregory Solyar called “Flying Space.”

Other guest speakers included Professor Reza Sarhangi who is a professor of mathematics at Towson University and President of Bridges. The professor gave a speech on mathematics called “Mathematical Connections in Art, Music, and Science The Art and Mathematics of Star Polygons.”

The final guest speaker the night was Dr. Alexander Dudelzak, the Senior Science and Technology Advisor at The Canadian Space Agency and the Director of R&D at GasTOPS LTD. Ottawa. Dr. Dudelzak gave a talk entitled “Novel Concepts and Applications of LIDAR From the Bottom of the Ocean to Mars.”

Lenox laser had another great success on its hands with the second seminar. Look forward to reading more about other seminars in the coming weeks.

Lenox Laser’s First Annual Light Seminar

Lenox Laser is and always has been part of so many monumental achievements. On October 4, 2010 Lenox Laser hosted their first annual light seminar commemorating the 50th anniversary of the creation of the laser to share in their wealth of knowledge. The gathering would not only serve as a testament to what Joe d’Entremont and the fantastic team that Lenox laser started, but as an educational history as well.

Guests included NASA astronomer Dr. John Wood who was a lead engineer on the Hubble telescope helping with optics in the 1990s. Dr. Wood was in attendance to discuss and demonstrate important principles of astrophysics. Some of Dr. Woods accolades include a NASA Exceptional Service Medal in 1992 and a NASA Exceptional Achievement Medal in 1994. Lenox Laser is honored to have hosted such a renowned scientist.

Other speakers included Lenox Laser’s own director of engineering, Gregory Solyar. Gregory joined Lenox Laser in 2006 as an optical scientist. There was also Stephen D Fanton, the founder and CEO of Optikos Corporation which specializes in manufacturing optical meteorology systems and designs optics-based products. Last but certainly not least, there was Dr. Dennis Zembala who is an advisor for many cultural museums, organizations and projects.

Perhaps the biggest moment of the night was honorary guest and keynote speaker, the late Dr. Charles Townes. Dr. Townes was awarded the Nobel Prize in 1964, the National Medal of Science in 1982 and the Templeton Prize in 2005. He was the inventor of the Maser, which is the predecessor to the laser. Dr. Townes spoke eloquently about how things began and how he stumbled upon creating the maser. His speech was titled “How New Things Happen.” Dr. Townes got his start working with radar around the time of World War II. An excerpt from Dr. Townes speech. “Well now, as for the Maser, and the laser, they came about not by accident, the buyer hard effort on my part. I was using microwave amplifiers to study molecules. How did that happen? Well again, by accident. I went to Bell Labs to do physics, but at that time war was coming along, World War II, and they sent me to do radar.” The evening was a smashing success and Lenox would go on to host two more light seminars in 2011 and 2012. Look forward to more information on those exciting events in the coming weeks.

The Archimedes Palimpsest

The mysteries of the past can sometimes only be revealed using new and innovative technology. This is the story of the Archimedes Palimpsest. The great Greek mathematician Archimedes left behind 3 books or codexs that we are aware of known as codex A, B, and C. Codex C is known as the Archimedes Palimpsest because the book was taken apart, washed of all its knowledge, and the paper was reused as a prayer book. Codex C was published in 1915 by Johan Heiberg using only a microscope. However this publication was incomplete. For years the book rotted away until one day it ended up in the hands of curator William Noel at the Walters Art Museum in Baltimore, Maryland in January 1999.

The palimpsest restoration project lasted well over eight years and was an immensely arduous task. Walters used multispectral imaging to enhance the writings on the paper, as well as radiation imaging. Given the codex shape, pages missing, and sections being unclear, many treasures couldn’t be seen before in the text. It is hard to know exactly how old the texts may be. A team of imaging scientists at the Walters Art Gallery carefully used highly focused x-ray florescent lights and infrared to carefully view the manuscripts as clearly as possible.

SLAC issued a request to Lenox Laser to produce microscopic laser-drilled holes in thin tungsten film when confronted with an engineering challenge involving their Synchrotron X-Ray source. These small apertures proved critical to the team’s success in uncovering the Palimpsest’s “hidden treasure” as they helped make previously unreadable sections of the document clear. This is just one of Lenox laser’s many pioneering moments in its history.

The Archimedes project would uncover a possible forgery in Archimedes’s Equilibrium of Planes, even one small section that portion would take over 10 hours for technicians to generate. Another amazing result was the team was able to find a whole column of text on the palimpsest. Thanks to the help of everyone involved in this project so many different fields, Codex C is now available to anyone through the Walters Art Museum.

NASA Series: James Webb Telescope

Space has always been a sea of possibilities for humanity to explore and grow our ever-evolving knowledge of the universe. In March 2021, that knowledge will begin to grow exponentially as NASA’s James Webb telescope is expected to launch. The telescope is named for NASA’s second administrator, James E Webb. The primary objective of the mission will be to examine the first light of the universe, along with the study of planets and how they evolve over time. The Space Telescope Science Institute (STScI) in Baltimore, Maryland will serve as an operations center for the James Webb telescope project. The planned mission duration is five years with a goal of 10 years. It is the hope of scientists that the telescope can measure subjects completely in infrared.

NASA Rendering of the James Webb Telescope

The idea of the telescope started as far back as 1986. The project survived cancellation attempts for its launch in July and November of 2011. It was demoed back in 2000, with its full name being granted in September 2002. The telescope was given a prime contract of $824 million in January 2007. The satellite instrument testing would happen between March 2016 and June 2018, with such things as telescope construction completion, cryogenic testing of instruments and mirror and optics installations.

Lenox Laser is honored to have provided the James Webb telescope with precision alignment targets for its mid-infrared instrument (MIRI). Optical scientist Richard Lyon was kind enough to open Lenox Laser’s industrial Institute of Optics first-class. He was working on the telescope in 2011. Mr. Lyon gave an extensive explanation of the telescope, its progress, and the optical science within the telescope. As the founder of Lenox Laser, Joe D’Entremont was invited to see this process firsthand. Lenox Laser wishes the James Webb mission a very prosperous and successful journey. We hope you have enjoyed this blog series and remember, never stop reaching for the stars.            

Lenox Laser will continue with a new blog next week. Now that we have explored our future over the past two months we will explore our past with the story of the Archimedes Palimpsest.
