U-14 Monochromatic Reflex Interference Viewer
(For use with 14" Optical Flat)
Designed for rapid production inspection with maximum precision on polished or lapped work. In the Van Keuren Reflex Viewer, the Optical Flat is secured above the light in a fixed cell; the work is placed on top of the flat and bands noted. Keeping the work on top of the flat avoids serious distortion due to the weight of the flat when the work is small or delicate. Work larger than the flat can be inverted and moved across the flat for two or more observations. Handling of the optical flat is entirely eliminated and risk of accidental damage or excessive wear is greatly diminished.
