Pinhole Photography Experiments at Lenox Laser


Lenox laser is presenting a look into pinhole photography being used to capture the details of a laser experiment. If you are new to pinhole photography visit our previous blog (What Is Pinhole Photography.) Josh Anderson and Joe d’Entremont used some everyday items such as a wedding ring, a lightbulb and tubing to capture the drastic detail of each item giving them a unique look. Credit to all pinhole photos here go to Josh Anderson and Joe d’Entremont.

Pinhole photo of G25 vintage Edison light bulb with 5 mW for effect

5 mW laser pointers were pointed at the base of a G 25 vintage Edison light bulb in this image. Given that red and green lasers were used in almost gives a sense that you can see gases inside the lightbulb. Camera used was a Canon 70 D.

This photo shows plastic neon translucent rods and flash speed light that captured the stillness of the warm neon glows. Camera used: Canon 70 D.

Pinhole photo of gold wedding ring in multiple locations.

Shows a gold wedding ring and it captured movements giving the sense that there are four while there is only one. This was done by locally illuminating the ring with the flash then moving the ring to its new location in the dark.

Pinhole photo shows a clear tube inside of the plastic sleeve with 5 mW laser pointers being used for the effect.

A clear tube was placed inside a 3 sided Styrofoam sleeve. The camera was looking down the center of the tube while the laser pointers were pointed at the tube at a 45 degree angle towards to bottom corners of the Styrofoam channel. While taking the photo the laser pointers were lightly shaken to give the desired effect.

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.

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.

Precision Laser Drilling for Custom Optical and Flow Calibrated Applications


The Lenox Laser Corporation is a high technology research and development company specializing in the application of small hole technologies. The company has pioneered the precision micro drilling of small holes (as small as 1 micron or smaller) into a variety of materials including advanced metals, glass and plastics largely used in filtering light, gas, liquids and particles. Developments in precision calibrated products have limited competition. The company’s research programs investigate current and future uses of the technology by engineering and experimenting with different industrial applications. Special performance requirements are achieved by inventing, applying or combining new processes. Many unique products result from this research.

Products manufactured by Lenox Laser are used extensively by industrial manufacturers. The company is often challenged to do what no one else can. The company in cooperation with corporate, academic and institutional research facilities has developed an information exchange that keeps it on the cutting edge of technological innovations. Technical advancements enhance the services offered at Lenox Laser and remain the cornerstone of product creations.

Lenox Laser manufactures optical component products, such as, apertures, slits, spatial filters, arrays and pinhole mirrors. One of the hottest selling items provided by Daystar Laser, the online distributor of Lenox Laser standard products, is a prefabricated “Aperture Kit” designed for convenience and eliminates time delays when custom orders are not required. The quality of Lenox Laser optical components has resulted in the company capturing a dominant market share in the United States and abroad.

Lenox Laser also delivers precision calibrated orifices to the semiconductor industry as a component for flow control. The advances in precison laser drilling pioneered at Lenox Laser have revolutionized industrial standards. Many of the applications that previously relied upon valve flow control devices are using Lenox Laser’s precision calibrated orifices. One significant advantage of replacing these devices with precision calibrated orifices is the ability to consistently control the accuracy of flow measurements. A second significant advantage is their time saving reproducibility. Highly skilled technicians use state-of-the-art equipment for the mass production of very high quality components. Precision calibrated flow control products are the new standard. Ongoing research with major industrial companies and well recognized technical colleges and universities has provided Lenox Laser with special projects of great potential to the semiconductor industry.

Massively Parrallel X-Ray Holography using Pinhole Technology


BERKELEY, CA – The pinhole camera, a technique known since ancient times, has inspired a futuristic technology for lensless, three-dimensional imaging. Working at both the Advanced Light Source (ALS) at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory, and at FLASH, the free-electron laser in Hamburg, Germany, an international group of scientists has produced two of the brightest, sharpest x-ray holograms of microscopic objects ever made, thousands of times more efficiently than previous x-ray-holographic methods.

Pinhole Photography Competition with Goucher



Lenox Laser made a visit local Goucher College to discuss an innovative new Pinhole Photography study and competition for Goucher College’s nearly 1300 students. Andrea Loepker, school Program Assistant of the Office of International Studies, already runs an International Photography Contest. (Winners are pictured to the right.)


Lenox Laser hopes to form a partnership with Goucher to help students discover the principles and valuable lessons to be learned from Pinhole Photography Science. Our goal is to set up an annual Pinhole Competition on Campus, to complement the department’s existing competition, as well as introduce a new medium to students.

Company President, Joe d’Entremont met with Goucher Vice-President and Academic Dean, Michael Curry, proposing an upcoming visit to Lenox Laser’s production facilities. It is our vision to work with Goucher in order to aid local students in building upon sound foundational sciences to develop and refine today’s technologies.
