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.
Zinc selenide has low absorption to infrared wavelength and can transmit visible light. It is the preferred material for making infrared lens, window, output coupling mirror and beam expander.
ZnSe lens is widely used in CO2 laser processing industry, including laser cutting, engraving, marking, drilling and other laser systems. The produced zinc selenide focusing mirror is made in China and imported. The lenses produced can withstand high power density, and the surface film layer is firm, easy to fall off, and resistant to wiping. After zinc selenide double-sided plating, it is used in the common working band 10.6 in CO2 laser industry μ The transmittance of M can reach 99%.
Positive meniscus (convex) lens is designed to reduce spherical aberration. When combined with another lens, the positive meniscus lens can reduce the focal length, so as to increase the numerical aperture (NA) of the system without introducing obvious spherical aberration. When used to converge parallel light, the convex surface of the lens shall face the light source to reduce the spherical aberration.
Negative meniscus (convex) lens is designed to reduce spherical aberration in optical system. When combined with another lens, the negative meniscus lens can increase the focal length and reduce the numerical aperture (NA) of the system. When used to converge parallel light, the convex surface of the lens shall face the light source to reduce the spherical aberration. Silicon (SI) material and silicon lens are also common infrared optical materials and chemically inert materials. It has high hardness and insoluble in water. It has good light transmission performance in 1-7um band. At the same time, it also has good light transmission performance in 300-300um far-infrared band, which is the characteristic of other optical infrared materials. Silicon single crystals are usually used as substrates for 3-5um medium wave infrared optical windows and optical filters. Because of its good thermal conductivity and low density, it is also a common material for making laser mirrors.
