In a Fresnel lens, the outer refracting surface is compressed to a flat plane. The Fresnel lens is composed of a number of concentric grooves that refract light. A Fresnel lens can be designed to perform a number of functions, including focusing, energy collection, collimation and diffusion. These types of Fresnel lenses can be used in applications such as imaging, lighting, and passive infrared sensors.
Features:
�� Designed for wavelengths between 5 and 20 microns.
�� Peak transmission between 9 to 12 microns.
�� Short focal lengths for low profile sensors
�� Optical surfaces are designed using Reflexite's proprietary design software
