12.7 mm N-BK7 uncoated corner cube retroreflector

Corner cube Prism is also named retroreflector or trihedral prism.In the corner cube prism,three reflecting surfaces are perpendicular to each other,like the side wall of the cube.The input surface is perpendicular to the cube diagonal. Disregarding the anlge of the incidence,the output beam is parallel to the input one,but it is of opposite direction. Inset of the several corner prisms, for better matching,their extrance exit surface is often hexagonal.In case of this glass prism the phenomenon of full internal reflection occurs so it is not necessary,(however it is possible) to put mirror coating on the reflecting faces. Normally the reflection surfaces are AL reflection coating, and then covered with Cu and Black painting. 

We supply a wide range of different materials of high precision optical glass prism,such as wedge prism,right angle prism,rhombohedral prism,Dove prism,Penta prism,pyramid prism,dispersion prism,beamsplitter prism etc.each having a particular geometry to achieve the reflections necessary to perform a specific imaging task.

BK-7 can be used for a range between the visible and infrared light.Fused-silica can be used for a range between ultraviolet and infrared light.
