DeLn Optics can provide Amici prisms, Schmidt prisms, Roof Penta Prisms, Roof Half Penta prisms and Roof Rhomboid Prisms, other roof prism specified by customers. With the roof surface, these prisms are used to invert and reverse the image.

 

Amici prisms, also called “roof prisms” or “right angle roof prisms,” revert and invert the image as well as bend the line of sight through a 90°angle. Ideal for use in spotting scopes, and any optical instrument where it is desirable to take an inverted image from an objective, turn it right side up, and bend it through a 90° angle in order to maintain the correct visual orientation.

 

Schmidt prisms are ideal for creating a right handed image with a ray deviation of 45°. They are similar in function to Amici 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 5 arc second roof angle tolerance increases the prism’s resolution. Schmidt Prisms can be combined with Half-Penta Prisms to create a Pechan prism.
