Infrared optics are used to collect, focus or collimate light in the near infrared (NIR), short wave infrared (SWIR), mid wave infrared (MWIR) or long wave infrared (LWIR) spectra. The infrared spectrum falls into the 700 – 16000 nm wavelengths, with each spectral range as follows.
NIR 700 – 900nm
SWIR 900 – 2300nm
MWIR 3000 – 5000nm
LWIR 8000 – 14000nm
Fluoride optical crystal products include calcium fluoride (CaF2), barium fluoride (BaF2), lithium fluoride (LiF) and other alkaline earth metal ion fluoride crystals. The range of transmittance of this series of crystals is 0.11~12.5 um, which makess them excellent ultraviolet and infrared optical materials. They are widely used as infrared window, optical lens, prism, wave plate, objective lens and other optical applications.
