We supply many types of high precision optical prisms,such as Wedge Prism,Right Angle Prism (Rectangular Prism),rhombohedral prism,Dove prism,Penta Prism, Roof Prism , pyramid prism,Dispersion Prism,Corner Cube Prism etc.each having a particular geometry to achieve the reflections necessary to perform a specific imaging task.Reflecting prisms may invert,rotate,deviate ordisplace a beam. Dispersion prism produce spectral separation for spectroscopic applications or for tuning a laser output.Wedge prism is commonly used in laser system for eliminating the reflections from the second surface or for beam steering.Irregular-shaped or non-standard size Glass Prism available by custom order.
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 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.
