COE offers many kinds of high precision prisms, i.e., right angle prisms, corner cubes, Penta prisms, dove prisms, roof prisms, rhomboid prisms or other irregular shape, which are made from optical glass BK7, fused silica, sapphire etc. Many types of prisms each have a particular geometry to achieve the reflections necessary to perform a specific imaging task. Reflecting prisms may invert, rotate, deviate or displace a beam. Dispersing prisms produce spectral separation for spectroscopic tuning a laser output.
