IR Filters

Hangzhou Shalom EO offers both broad band pass infrared filters and narrow band pass IR filters, for manifold applications including IR Thermal Imaging & Thermal Sensing, IR Thermography, IR light Emitters & Detectors,etc.. These filters are made from various IR substrates such as silicon, sapphire, IR Quartz, germanium, ZnSe, ZnS, CaF2, etc. processed to the form of thin films, that have differing refractive indices and thicknesses. The filters performs high efficiency while isolating emission lines from a source or fluorescent from background, or laser lines to maximize the signal relative to noise ratio.

Our Broad band IR filters and Narrow band IR filters either cut or let pass light respectively , with corresponding wavelength of interest that covers the whole IR range of 0.9μm - 12μm. Any wavelength within the range could be blocked or transmitted/isolated according to your needs, with high transmission rate which peak%s to nearly 98%. All of the specifications of products could be customized upon your request. Feel free to contact us for consultancy, our experienced and professional engineer are always willing to guide you to a optimized solution.
