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.

(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.

OST Photonics Cylindrical Lenses Cylindrical lenses are utilized for astigmatism correction in the eye and rangefinders, inducing astigmatism by elongating a point of light into a line. They find extensive application in barcode scanning, projection optics systems, laser measurement systems, and holography. Ost Photonics offers cylindrical concave lens in plano-concave or plano-convex configurations. Basics about Cylindrical Lenses LENSES MATERIALS ILLUSTRATION PROPERTIES AND APPLICATIONS CYLINDRICAL LENS BK7/ Fused Silica/CaF2 /other optical glass Used to provide focusing power in one section only. For illumination or detection of light from line sources. Also used for the anamorphic compression of beams and images.

Cylindrical lenses are specialized optical components used primarily to correct astigmatism, a common refractive error in the eye. Unlike spherical lenses, which have the same curvature in all directions, cylindrical lenses have curvature in only one direction. This unique property allows them to focus light into a line rather than a point, making them ideal for applications requiring precise control over light direction and focus. OST Photonics, a leader in cylindrical optics, offers high-quality cylindrical lenses designed to meet various optical needs.
