Advantages of 850nm bandpass filter:
1. Suitable for working under strong light interference such as sunlight;
2. The maximum transmittance is over 95%, and the attenuation rate of the optical signal is small, effectively improving the working distance and light intensity;
3. It can be directly coated or glued on glass with visible light cut-off and infrared transmission, quickly improving the cut-off rate. When vertically incident, there is no penetration phenomenon under strong infrared lamps, and the transmittance is less than 0.2%. And ensure that the wavelength shift phenomenon is reduced when working at a large angle.
4. Ruicheng Optoelectronics has many years of experience in producing optical filters, using imported coating machines and IAD ion assisted coating technology to ensure low-temperature drift and stronger film stability.
