Prisms / Wedges
From the basic 90° right-angle prism to challenging prism assemblies, IRD glass has the experience and talent to fabricate exactly to your needs. Prisms with angular tolerances tighter than 3 arc-minutes can be accompanied with NIST-traceable certificates accurate to within 5 arc-seconds for the optical angle or angle of deviation. Anti-Reflective, Mirror, band pass and other thin film coatings are also custom-applied on a daily basis. Light wedges, corner cubes, rhomboid prisms, wedge prisms, penta prisms, dove prisms, roof prisms and many other variations are all finished to exacting specifications.
