Description: 

IR Lenses are used to collect, focus, or collimate light in the near-infrared, short-wave infrared, mid-wave infrared, or long-wave infrared spectra. IR Lenses are optical lenses that use specific substrates or anti-reflection coatings to maximize performance for applications operating above 700nm including thermal imaging, FLIR, or spectroscopy. The infrared spectrum refers to 700 – 16000nm wavelengths. When divided into smaller spectra, NIR refers to 700 – 900nm, SWIR is 900 – 2300nm, MWIR is 3000 – 5000nm, and LWIR includes 8000 – 12000nm wavelengths.

GIAI Optics offers a large variety of IR Lenses including singlet lenses, achromatic lenses, aspheric lenses, or focusing objectives for high performance across a large portion of the infrared spectrum. IR Achromatic Lenses are ideal for use in a variety of industrial, life sciences, or defense applications including FTIR spectroscopy or for use with tunable QCL lasers. Zinc Selenide IR Aspheric Lenses feature diffraction limited designs that are ideal for focusing the output of CO2 lasers. Additional substrates include germanium, sapphire, silicon, zinc selenide, or zinc sulfide. Anti-reflection coating options include VIS-NIR, NIR I, NIR II, Telecom-NIR, or SWIR.
