An IR lens is a lens component optimized for light processing in the infrared region (that is, the spectral portion with wavelengths between 7000 and 20000nm), including Near-Infrared (NIR), Shortwave Infrared (SWIR), Midwave Infrared(MWIR), and Longwave Infrared (LWIR). With selected IR-transparent substrate materials and anti-reflection coatings, Hangzhou Shalom EO is capable to manufacture IR lenses that are compliant with a wide assortment of Infrared applications, including Thermal Imaging, Forward-Looking Infrared (FLIR) Cameras, FTIR spectroscopies, CO2 Lasers, etc.
Hangzhou Shalom is an adept global supplier of IR Lens Components, our broad infrared lens production portfolios include Plano-convex IR Lenses, Plano-concave IR Lenses, Meniscus IR Lenses, Aspheric IR Lenses, Ball/Half-Ball Lens, etc. to achieve diversified functions as to focus, collimate, and collect lights. (Besides the lenses, aluminum reflective mirrors designed for LWIR and MWIR long-focal-length thermal cameras are also accessible.) In Shalom EO, the production efficiencies and processing acuteness of the IR lens are enhanced using the CNC and Single Point Diamond Turning (SPDT) techniques. Before dispatch, strict QC inspections are carried out to secure your interests.
IR Lens components made from various substrate materials are available in Shalom EO, including Germanium (Ge), Silicon (Si), Zinc Selenide (ZnSe), Chalcogenide Glass, Sapphire, Calcium Fluoride (CaF2), Barium Fluoride (BaF2), Zinc Sulfide(ZnS), with their working wavelength range encompassing multiple Infrared wavebands. Coating options include broadband anti-reflection (BBAR) coating, long-pass anti-reflection coating, DLC coating, etc. Germanium Lens features a broad transmission range from 3-14 micro and a significant refractive index, hence is often incorporated in thermal camera lens assemblies. The ZnSe meniscus/aspheric lens exhibits low spherical aberration and is excellent for CO2 laser output and MWIR pulsed lasers. The chalcogenide glass lens has eminent thermal properties and is ideal for designing cost-effective athermalized lens modules. Sapphire lens features unrivaled mechanical strength, and thermal and chemical resistance, being recommended for high power/pressure conditions and harsh environments. Whilst CaF2 Lens demonstrates high optical transmission and low chromatic dispersion.
