This is a Tropel Model 9000 laser interferometer. It is used for checking the flatness of wafers and masks up to 5 inches in diameter. It uses a HeNe laser as a monochromatic source, and has a built-in video camera for fringe display on a Sony Black & White monitor.

The interferometer is in spectacular condition with the exception of a small scratch near the upper center of the reference prism (outside the field of view of all but the largest wafers). The wafers are held in place by a vacuum chuck and fringe spacing and direction is adjusted via three very fine setting screws located to either side and beneath the chuck holder.

The interferometer includes the following chucks:
� 2 inch vacuum chuck
� 3 inch vacuum chuck
� 4 inch vacuum chuck
� 5 inch ‘bow’ chuck
