Black Color Glass IR Filter Optical Narrow Bandpass Filter

Black Color Glass IR Filter Optical Narrow Bandpass Filter Product Description: The bandpass filter produced by NMOT adopts dielectric hard-film coating technology and the principle of dielectric interference. On the basis of highlighting the characteristics of narrowband filter, its optical performance is independent of the thickness of the substrate, which make it more convenient to be built into the instrument imaging system, improve the optical performance and realize effective application. The use of special optical material substrate has solved the problems of fog prone and optical performance instability of traditional absorbent synthetic glass. The product can be produced according to the customer's index requirements. Yisu Photonics' main products include: precision optical lenses, prisms, optical lenses, field lenses (ultraviolet, optical fiber, CO2), galvanometers, narrowband filters, band pass filters, long and short pass filters, laser equipment lenses , Gold-plated silver-plated aluminum reflector, drone lens, attenuator, beam splitter (semi-transparent mirror), window (AR), beauty equipment filter, biomedical filter, infrared cut filter , Smoke sensor lens, focusing lens, etc. Widely used in attendance machines (handprint, palmprint, vein and face recognition), security monitoring systems, anti-counterfeiting recognition systems, smart lamps, cabinet sensor systems, stage lighting and laser demonstration systems, projection optics, laser devices, and Biochemical medical optics.
