Making Foamcore Kits for a Class

This will allow up to a six inch focal length. Smaller focal lengths can be cut down from there. [I mark pieces #1-4 at one inch intervals to make it easier for students to cut to the focal length they want]

If you are an instructor and want to make "kits" for your students , you can make 5 generic 6" focal length foam core pin hole cameras from each piece of 32x40 inch foam core board.

The dimensions become:

Pinhole plane - 4 3/4 x 6 1/16
Film Plane - 4 3/4 x 6 1/4
#1 - 4 3/4 x 6 1/2
#2 - 4 3/4 x 5 13/16
#3&4 - 6 7/16 x 6 1/2

Support Struts:
4 3/4 x 1/2 make at least 4 for each camera [2 for film plane and 2 for pinhole plane]
5 9/16 x 1/2 make at least 4 for each camera [2 for film plane and 2 for pinhole plane]

There is enough material left over for the one or two people making adaptions, like double slit or multi-hole cameras.
