Infrared (IR) Right Angle Prisms are available in three substrate options. Calcium Fluoride is a low index (1.434) material with excellent transmission from 0.19 - 7μm, making it ideal for applications throughout the UV, Visible, and Infrared spectra. Germanium is a dense material with a high index (n10.6μm = 4.0034), making it ideal for applications from 3 - 12μm where the optical path length needs to be maximized. Zinc Selenide (n10.6μm = 2.4028) is commonly used with CO2 laser applications, and features high transmission from 1 - 16μm.
Right angle prisms are generally used to bend image paths or redirect light at 90°. This produces a left handed image and depending on the orientation of the prism, the image may be inverted or reverted. Right angle prisms can also be used in combination for image/beam displacement.
Note: Special care should be taken when handling Zinc Selenide as it is a toxic material. Always wear rubber or plastic gloves to avoid risk of contamination.
