Infrared Optics
Infrared optics are optical elements focused on the propagation, manipulation, and utilization of light within the infrared spectrum. Infrared wavelength band means wavelength range above 700nm, in general, it can be divided into four smaller spectra: near-infrared (NIR) at 700nm-900nm, short-wave infrared (SWIR) at 900nm-2300nm, mid-wave infrared (MWIR) at 3000nm-5000nm, and long-wave infrared (LWIR) at 8000nm-16000nm. Infrared or IR optics are often used in Forward-looking Infrared (FLIR), Fourier Transform Infrared (FTIR) spectroscope, SWIR imaging, MWIR, LWIR thermal imaging and detection, defense, aerospace, industrial processing, and excimer/semiconductor/CO2 lasers.
Hangzhou Shalom EO offers singlet IR optical lenses, IR optical windows, and domed windows, in addition to assembled lens modules designed for SWIR (0.9-1.7 micro) imaging, MWIR (3-5 micro) and LWIR (8-12 micro) thermal imaging camera lenses. Various specific infrared optical materials are available: Germanium, Zinc selenide (ZnSe), Zinc sulfide (ZnS), Chalcogenide glass, Silicon, Sapphire, and Fluorides (CaF2, BaF2, MgF2, and LiF). Our fabrication techniques include conventional polishing and diamond turning, and our optics types include flat surface, spherical, and aspherical surface optics.
