Interference filter ( photosensitive resistor )

Optical properties: infrared cut-off bandwidth, low transmittance, effectively prevent infrared ray, improve photosensitivity. Imported 0.55mm thin optical glass, light transmittance and good flatness, the introduction of Germany coating production equipment, strict spectrophotometer each piece are more than 5 points detection. Ensure product stability, consistency, temperature drift! The center wavelength of film firmly of the strong, no color uniformity, smoothness, U.S. standard A-level CNC precision optical glass edge grinding, size control in 0.02mm--0.05mm, edge collapse is small, no burr, the appearance of a good finish!

Specifications:φ 4.7mm/ φ4.8mm/ φ5.0mm/ φ5.1mm ( have long-term inventory )

We supply security monitoring filter photosensitive resistance shock @ professional infrared filter, 850nm, 940nm band, 780nm band, 808nm band, 905nm band, 980nm band type filter is applied to the gate LAN security system, infrared transparent acrylic board and injection molding products applied to wireless speaker, an infrared receiving and other optoelectronic and electronic products. Our products and the attenuation sheet, grating, a spectroscope, a front surface mirror, RGB mirror, lens, antireflection glass, filter strips used in optical instruments, biochemical and medical equipment photoelectric sensing device. On the other can be customized for various optical coating products security monitoring filter photosensitive resistance can be suitable for high precision optical instrument, infrared flip remote control, infrared ink recognition, automatic Zhitong equipment, biometric recognition, iris recognition and other equipment.

Division I in 2009 launched a high definition, inhibition of super light interference identification filter ---850nm filter that is photosensitive resistor used in bright light cameras general beat not to license plate or taken is not always clear, camera, will be less and less! Through the improvement of technology, from the quality and decrease the band pass filter cost, Division I with a large number of photosensitive resistance.
