Technical indicators center wavelength: 940 ± 5nm bandwidth: 30 ± 5nm peak transmittance:> 85% cut-off range: 400-1100nm deadline Depth: Tave <0.5% Size: customized technical features: all-dielectric coating technology to achieve all of the optical properties , independent of the optical properties of the substrate thickness, the thickness can be thin, so that it can be built into the camera inside. Because absorption is not used as the base color of the glass, so good filter stability, not easy to mold or hair spray.
