Infrared Optics

Infrared wavelength band means wavelength range above 700nm, 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 Spectroscopy (FTIR) spectroscopy, SWIR imaging, MWIR and LWIR thermal imaging and detection, and CO2 lasers

Hangzhou Shalom EO offers not only singlet IR optical lenses, IR optical windows and domed windows, but also the assemblied lens modules designed for MWIR (3-5 micro) and LWIR (8-12 micro) thermal imaging cameras. A variety of specific infrared optical materials are available: germanium, Zinc selenide (ZnSe), zinc sulfide (ZnS), chalcogenide glass, silicon, sapphire and fluoride (CaF2, BaF2, MgF2 and LiF).  Our fabrication techniques includes conventional polishing and diamond turning, our optics types includes flat surface, spherical and aspherical surface optics.
