TECHSPEC® Pechan Prism
TECHSPEC® Pechan Prisms leverage Edmund Optics' manufacturing expertise to deliver a precision inline instrumentation prism to rotate an image by 180 degrees. This image rotation is employed in many direct view applications and replaces a relay prism or lens system for a more compact optical train. Overall clarity of the system is ensured by adding both an anti-reflective and metallic coating to each prism. The TECHSPEC Pechan Prisms feature 5 arcsecond roof angle tolerances to maintain image resolution.
