CaF2 Window&Lens, Optical Lens, Precision Optical Window

Product Specifications

Product Description

CaF2 Windows
• The Window is made from Calcium Fluoride material, which has transparent range from 170-7800nm. The refractive index is 1.399 at 5000nm. It has little hygroscopic susceptibility and high thermal expansion coefficient. CaF2 Windows are relatively soft and somewhat hygroscopic so polishing, coating and handling are more critical than UV Fused Silica windows. In addition, The quality of a UV window can be extremely critical, it should be of high purity and polish in order not to affect the optical system. Calcium Fluoride Windows are also applicable for a wide range of spectrum. It is particularly useful for wavelength at 2980nm laser application.

CaF2 Lens of ICC
• CaF2 are used to split or combine beam of light.The most common types provided by crylight are;plate and cubes.Plates are used for most laser applications as they ehibit low absorption.Cubes are a convenient ,protected form for low power applications.The performance of CaF2 are mainly dependent on the coating specifications.For the coating curves of eavh types of CaF2 ,please refer to Coating chapeter for more information.Inselecting CaF2 window,tye type,coating transmission range and damage threshold should be considered.


Optics and optical components of CaF2 Lens
• Optics and optical components cover all manner of devices that are used to manipulate or control light. These components either use electrical or electronic means to manipulate light, such as occurs with lasers, diodes, photomultipliers and optoelectronic sensors, or they can force the manipulation via material means. This second grouping includes items such as lenses, filters, beamsplitters, mirrors, diffusers, plates, prisms, and windows. A subgroup of this category is fiber optics. Items within the optics and optical components category fall into four loose families: light sources, optical components, optoelectronics, and fiber optics. This grouping includes all products that are used to transmit light via transparent glass or plastic fibers. Optical components are items that are used to bend, split, diffuse, reflect or otherwise alter or refocus light wavelengths.
