Variable Lens Board for a Digital System


A lens board and Nikon adapter for a digital camera system. The lens board was fabricated using the specifications taken from the original board. A Nikon mounting plate (with locking pin) was then attached.


Because the exact distance from the lens-bearing surface to the focal plane was not known, an adjustable ring system was designed. See below for a close up image.


The rear components of the adapter ring also featured a 67mm filter thread. When screwed into the adapter, the filter sits approximately .025 from the rear of the lens, thus eliminating vignetting and allowing for enough clearance for the camera’s digital trap door.
