The HWB800 / RG800 infrared transmitting filter is manufactured from black optical filter glass. It is designed to absorb or block most visible light while transmitting near-infrared wavelengths around 800nm and above. Its selective spectral performance helps reduce visible-light interference and improve infrared signal detection and imaging contrast.
This filter is suitable for infrared cameras, night-vision systems, infrared sensors, machine vision, photoelectric detection, infrared LED illumination, laser measurement and scientific instruments. Each filter is precision-ground and polished to provide reliable optical quality and dimensional accuracy.
Circular, square and custom-shaped filters are available. Customized processing services include thickness adjustment, cutting, edge finishing, beveling and optical coating.
The actual cut-on wavelength, transmittance and spectral curve may vary depending on the glass grade, thickness, angle of incidence and production batch. Because HWB800 and RG800 may belong to different materi
