Product Description

Cast acrylic sheet features an average transmittance of over 90% from visible light to mid-infrared band. With merits of high hardness, high light transmittance, good heat resistance and excellent dimensional stability, cast acrylic is a widely used optical material. By adding infrared absorber into optical-grade sheet, visible light can be blocked while infrared transmission remains unaffected. The sheet thereby obtains light filtering performance while retaining its original thermal properties.

Application Fields

Iris recognition, wireless transmission equipment, infrared interactive whiteboards, infrared cameras, infrared touch screens, infrared medical instruments, infrared ink recognition, facial recognition sensor systems, handheld infrared laser rangefinders, laser distance meters, optical instruments, medical & healthcare equipment, testing instruments, etc.
