IR Right Angle Prisms

Edmund Optics (EO) has introduced IR Right Angle Prisms, which are used to achieve a 90º (Right Angle) light path bend.

Edmund Optics' IR Right Angle Prisms are available in three substrate options to cover a wide range of applications. Calcium Fluoride, a material with a low index of refraction of 1.434, provides excellent transmission properties from 190nm to 7µm. This substrate is ideally suited for applications throughout the UV, visible and infrared spectra. Germanium is a dense material with a high index - excellent for applications in the 3-12µm region where the optical path length needs to be maximised. Zinc selenide, commonly used in a variety of CO2 laser applications, features high transmission from 1-16µm.

These uncoated prisms utilise total internal reflection for the right angle path bend and are perfect for use with well-collimated light sources. EO's IR Right Angle Prisms with a calcium fluoride substrate are available uncoated in 12.7mm, 25.4mm and 38.1mm sizes. IR Right Angle Prisms with a Germanium substrate or a Zinc Selenide substrate are available uncoated in 12.7mm and 25.4mm sizes.
