Development of the LE-Adapter ( Lens Adapter )

Most inventions are a result of not being able to perform a wanted task with pre-existing tools or methods. The old adage "Necessity is the mother of invention" more than adequately describes the reason the LE- Adapter was developed.

Below is a brief description of the development of the LE-Adapter authored by Bill Benz, the inventor.

In 1982 I was a consultant in the magnetic disk industry in Silicon Valley, Ca. and wanted to photograph different microscopic defects that were seen on reject disks through a 3x to 400x zoom microscope. I had just purchased a SLR camera that had automatic light metering capabilities and thought I could document the defects with this camera by merely attaching the lens to the eyepiece of the microscope.

I then began calling camera shops in the San Francisco area asking for a SLR camera lens to eyepiece adapter. Much to my amazement, they told me the only item available to take pictures through a microscope with an SLR camera was an SLR camera body to eyepiece adapter.

They further stated I would need a camera body to eyepiece tube adapter called a T-ring. The T-ring has a specific manufacturers camera body bayonet connection on one end and female threads on the other end that the fixed focal length microscope tube threads into (it should be noted that one must remove the lens from the camera body to mount the T-ring to the body of the camera thereby removing the automatic aperture/shutter adjusting capabilities of the SLR camera which in turn negates the automatic picture taking capabilities of a SLR camera).

I was further informed by a number of experts that it would be technically impossible to take a picture with the objective lens of an SLR camera coupled to a microscope eyepiece. One expert told me emphatically "It won't work"...I truly believe those words were the ones that set me to the task that it "would work"!

So I had a machinist at the company I was consulting for machine an annular ring that threaded onto the 50mm filter lens of my camera with a tube that extended so that it would slip over the eyepiece of the microscope.

Lo and behold...the camera took great pictures with the lens coupled directly to the eyepiece. The camera automatically set the proper focal length and exposure. The "experts" were was possible to directly couple a camera lens to an eyepiece and take perfectly exposed pictures.

Once I proved that one could couple the lens of a camera to an eyepiece, the next step was to make an adapter that would hold different diameter eyepieces. I had to devise a method to adapt eyepieces that were literally a couple of millimeters different in diameter distributed by various manufacturers of microscopes, telescopes, spotting scopes, etc.

I subsequently worked on different approaches to making a Universal Lens to Eyepiece Adapter and finally arrived at the present patented design of the LE-Adapter. The adapter simply consists of an annular ring with 52mm threads on one side and having a 1.6 inch diameter opening. Three plastic screws located 120 degrees apart impinge on a 1/2" wide tempered steel strip to clamp various size eyepieces to the lens. This design allows finite diameter clamping adjustments to couple the threads of most any lens to eyepieces ranging in diameter from .5 to 1.5 inches

The myriad advantages of the LE-Adapter coupling a camera lens to an eyepiece really came to fruition when Sony first introduced the TR-5 Camcorder in 1990.

The small hand held video camera opened a whole new world for the LE-Adapter. One could now attach a telescope or a nightvision scope as well as high magnification binoculars or spotting scopes to a device that has very low light capabilities. The light gathering capability of a camcorder translates to a film-speed equivalent of 10,000 to 20,000 ASA. The zoom lens of camcorders also benefits the LE-Adapter versatility. For instance, using a 10x camcorder attached to a 10x spotting scope results in a 100x video picture or a simple 30x spotting scope coupled to the same camcorder results in 300x magnification with unbelievable resolution.

With the LE-Adapter connected to a camcorder or digital camera your ability to produce high-quality and truly interesting and exciting videos using telescopes, microscopes, spotting scopes, or even a nightvision scopes is now limited only by your own imagination.
