Product 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.
Biconvex lens consists of two spherical radii, which effectively eliminates coma, distortion and color difference. They are combined with other lenses to form an imaging system.
This type of lens is suitable for the following cases: the object and image are on both sides of the lens, and the ratio of image distance to object distance conjugate ratio is between 0.2 and 5.
K9 biconvex spherical lens has good transmittance in near infrared 350-2000nm.
H-K9LN-BK7 is an optical glass commonly used in the preparation of optical elements.
These uncoated biconvex lenses are prepared using H-K9LN-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.
