There are many types of opticalprrisms,such as wedge prisms,righe angle prism,rhombohedral prism,dispersing 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.dispersing prisms 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 prisms may be available by custom order.
