The 850nm bandpass filter is used in NIR imaging system to eliminate the influence of surrounding background light, including the visible and NIR light. This filter is to increase the signal/noise ratio of the imager. The applications include video surveillance, visual telephone, visual doorbell, digital telescope and other imaging systems.

Angle of incidence---------0° Substrate---------------------BK7, Float glass, B270, Borofloat33 Size-----------------------------Customized Application--------------------For image sensor that only requires NIR light. (The final detailed specifications are customized or suggested by Lenoptec. ) High visible light reflective mirror, also called Cold mirror, is designed to reflect the visible light at the reflectance of at least 90%, while pass the IR light at the transmission of at least 90%. Commonly applied to biometric devices that the sensor only requires NIR light to form the image. All Optical filters include: Acrylic Filter Dichroic Filter Beam Splitter Reflective Coating Interference Filter Waterproof and dustproof coating AR coating UV-IR Blocker IR Cut-off Filter Cartons
Plano-convex lens, aslo called positive lens, is used to converge incident light to a spot on the axis, at a certain distance behind the lens, which is knowed as focal length. It can form both real images and virtual images(for magnifier) on the two sides. The materials to make plano-convex lens can be BK7, Fused Cilica, sapphire and CaF2 etc., for different applications.This model are commonly applied in many devices including telescopes, collimators, magnifiers,optical transceivers, condensers and other optical display or imaging optical systems. AR/NIR or other coatings are available according to the applications.

Achromatic lens is designed to limit the effects of chromatic and spherical abberation. It is corrected to bring two wavelengths(typically red and blue) into focus in the same plane. Achromatic lenses can be doublets or triplets, with two or three individual glasses cemented together.
