Second Model
Model No.: 3002
Issued Date : May 1 2011
Material: The lens is from a piece of blue thick paper.
Findings :
The shape of hole is good, in perfect circle but light can cross the blue paper and make the photo in blue color.
The remedy is to make a sandwich lens, two pieces of blue thick papers hold a piece of video tape. It works.
The hole diameter is 0.5 mm.
Follow up : Testing the result of different sizes of hole and reading some reference books.
