BARRINGTON, NJ, July 23, 2009 – Edmund Optics Inc. has introduced its infrared right-angle prisms that are used to achieve a 90º light path bend. They are available in three substrate options to cover a wide variety of applications.

EdmundOptics-IR-Right-Angle.jpgCalcium fluoride, a material with a low index of refraction of 1.434, provides excellent transmission properties from 190 nm to 7 µm. This substrate is suited for applications throughout the ultraviolet, visible and infrared spectral regions. Germanium is a dense material with a high index and is suitable for use in applications in the 3-to 12-µm wavelength region where the optical path length must be maximized. Zinc selenide, commonly used in a variety of CO2 laser applications, features high transmission from 1 to 16 µm.

These uncoated prisms use total internal reflection for the right-angle path bend and are suitable for use with well-collimated light sources. The prisms with a calcium fluoride substrate are available uncoated in sizes of 12.7, 25.4 and 38.1 mm. Those with a germanium or a zinc selenide substrate are available uncoated in 12.7- and 25.4-mm sizes.

Custom antireflection and metallic coating options are available to meet customers’ specific requirements.
