Purpose: To view individually a pinhole "image."
Description: A pinhole in the back end of the outer box (left front) casts an "image" on a ground glass screen at the enclosed end of the inner box (front of box at right rear). The image is viewed through the open end of the box (at the rear) as the inner box is slid back and forth to change the size of the image
