PRODUCT OVERVIEW
Introduction
Silicon is a widely used infrared optical material with excellent mechanical strength, high thermal conductivity, and good transmission performance in the mid-infrared wavelength range. These characteristics make silicon windows well suited to optical designs that require a combination of infrared functionality and robust material performance.
Optically, silicon differs significantly from conventional glass windows because of its high refractive index and limited transmission in the visible region. Its spectral characteristics make it particularly useful when the optical design is intended to transmit infrared radiation while suppressing visible wavelengths, although the high surface reflectance typically makes anti-reflection coating an important consideration.
