Narrow bandpass optical filter 850nm FWHM60nm
1) Suitable for sunlight and other bright light interference work;
2) Transmittance up to 90%, and the optical signal attenuation rate is small, effectively improve the working distance and light intensity;
3) Can be directly coating or glue in the infrared transmittance glass by the visible light, rapidly increase the cutoff rate, the vertical incidence in strong light without penetration, light transmission rate is less than 0.2%. And to ensure that working in large angle,and short wavelength shift phenomenon reduction.
