Supply Plate Recognition 820nm narrowband bandpass filter

License Plate Recognition 820nm narrowband bandpass filter material: float glass or quartz glass incidence angle: 0 ° center wavelength: 820 nm FWHM: 20 nm peak transmittance: T> 90% at 820 nm cut-off depth: OD3- A Applications: machine vision, biochemical analysis, optical instruments Technical features: all-dielectric coating technology to achieve all the optical properties, optical properties independent of the substrate thickness, the thickness can be done very thin, so that there can be built into the camera. Because absorption is not used as the base color of the glass, so good filter stability, not easy to mold or hair spray.
