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.


The plano concave lens is used to diverge the parallel light outward. The focal length of the flat concave lens is negative and the spherical aberration is also negative. It can be used to correct the phase difference, spherical aberration, coma and distortion of other lenses. Similar to the flat concave mirror, the side is generally opposite to the far object surface or infinity.


K9 plano concave spherical lens can see the transmittance of near infrared (350-2000nm).


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


These uncoated plano concave 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.
