Detailed Description

Hanzhong Brisun Optics Co., Ltd. Is the high High precision optical element manufacturer provides customized production of Various optical lenses, including spherical lens, cylindrical lens, optical window, mirror, prism, filter, metal base mirror and other high-precision optical elements. The base materials include various optical glass, fused quartz, calcium fluoride (CaF2), zinc selenide (ZnSe), germanium (GE), silicon (SI), sapphire, metal and other materials. And provide antireflective film, high reflection film, spectroscopic film, metal film and other optical coatings.


Biconcave lens is similar to plano concave lens. The focal length is negative, but the light incident in parallel diverges outward. The curvature radii of the two sides of double concave lens are equal. It is generally used for beam expansion and projection.


K9 biconcave spherical lens has good transmittance in near infrared (350-2000nm).


H-K9L(N-BK7) is an optical glass commonly used in the preparation of optical elements.


These uncoated biconcave lenses are prepared using H-K9L(N-BK7) conforming to ROHS standard. The collimated beam can converge on the rear focus, or the point light source can be changed into a collimated beam.
