Edmund Optics Inc. 7.16mm Corner Cube Prism NT65-250

Incident Light is Reflected Back to the Source 3 Arcsecond Beam Deviation Ideal for Alignment Also Available Mounted Corner cube retroreflectors are designed to reflect any ray or beam entering the prism face, regardless of the orientation of the prism, back onto itself. A mirror will only do that at the normal angle of incidence. As a result, corner cube retroreflectors are ideal where precision alignment is difficult or time-consuming. They feature three total internal reflections and will function even at very large angles of incidence. TECHSPEC® N-BK7 Corner Cube Retroreflectors are made from precision N-BK7 for use in a variety of visible light applications.
