Ray Deviation of 45°
Right Handed Image
5 Arcsecond Roof Angle Tolerance
Combine with Half-Penta Prism to Create Pechan Prism
Schmidt prisms are ideal for creating a right handed image with a ray deviation of 45°. They are similar in function to Amici Roof Prisms, however the 45° deviation makes Schmidt prisms especially useful in eyepiece assemblies and imaging systems requiring a path bend. The aluminized roof surfaces enhance the overall efficiency while the 5arcsecond roof angle tolerance increases the prism’s resolution.Schmidt Prisms can be combined with Half-Penta Prisms to create a Pechan prism.
