The use of small master angle prisms optically contacted to a large prism offers a method for reduplicating reflecting angle surfaces of prisms by interferometric measurements. Optical working and testing procedures are described for making a typical prism-the penta prism was selected.
In optical figuring, pitch polishers with either cutout or scratched profiles are often used. Much time and effort are lost in trying to figure the optical element's surface with previously made up polishers. In a prior article, an optical design application of Japanese paper folding art is described. In our work we found yet another application of this… (More)
Testing of optical systems by the use of two wires situated in defocused positions gives qualitative and quantitative data on spherical aberration. The test device allows two knife edge tests to be made in addition to the double wire test. These three correlated tests minimize errors in interpretation.
Prisms with reflecting faces and angles of 2 sec or less can be made and tested by the use of a simple collimator. The collimator is set to autocollimate internally the angles made by the reflecting faces of the prisms.
