Product Description
China Manufacturer Zinc Selenide (ZnSe) Plano-Convex (PCX) Lenses
Oplens Optical can provide a variety of custom infrared optical lenses made of different IR optical materials. We offer cylindrical, plano-convex/concave and meniscus lenses, as well as achromatic doublets and aspherical options to reduce aberrations within the system.
Oplens manufactures infrared (IR) lens within the wavelength of 3~12μm. Our IR products can be applied to Thermal imaging, night vision, surveillance, life sciences and other fields.
In addition to the traditional cold machining of spherical and planar components, we can also process aspherical lenses by turning the surface with precision diamond lathe. This technology can be used to correct spherical aberration in optical systems. At the same time, we can make anti-reflection coating in the rage of 4~12μm, including high hardness (HD) and diamond like carbon (DLC) coating.
Technical Information
Zinc Selenide is a chemically vapor deposited material commonly used in thermal imaging, FLIR, and medical systems. It has wide usage in high power CO2 laser systems because of its low absorption coefficient and high resistance to thermal shock. Zinc Selenide is a relatively soft material that scratches easily and it is not recommended for use in harsh environments (Knoop Hardness 120). Great care must be taken during handling, mounting, and cleaning. Apply uniform pressure when handling, wear Latex finger cots or gloves to prevent contamination and do not use tweezers or other tools.

Processing
Oplens equipped Precitech SPDT with Taylor Hobson PGI 3D profilometer. The results of the profilometer measurement system can be directly put into the diamond machine to provide positive compensation values for the machining of aspheric components. At the same time, curvature, surface flatness, roughness and other indicators can be quantified effectively and accurately.
Testing
Oplens equipped Zygos which work by producing a beam of laser light and transmitting it to the optic under test by way of a very, very accurate lens fitted to the Zygo. This is the key to the instrument's accuracy. As the light passes through this lens, which is not coated, it enables 4% of the light to be reflected back into the Zygo.
Company Profile
Sichuan JUKA Optical Technology Co., Ltd. is a professional company specializing in high-precision optical lens, prisms, and window,etc. Company is located in Chengdu of China, which enjoys the fame of world-wide optical processing center. JUKA's predecessor was the Optical Processing Department of the Institute of Optoelectronic Technology, Chinese Academy of Sciences,which was established in 1988. And company switched successfully to be a private enterprise from a state-owned enterprise in 2005.
