Lightweight and cost-effective, silicon windows are optimized for the 1.2-7µm NIR-MWIR range. They are ideal for weight-sensitive IR sensors and thermal imaging applications.
Silicon windows are precision optical components designed to transmit light with minimal scattering or diffraction. Hengpu manufactures silicon windows in diameters ranging from 5 mm to 200 mm, with custom optical solutions available upon request. These windows are precision-engineered to introduce virtually no wavefront distortion, making them a highly cost-effective choice for a wide variety of optical applications.
