DESCRIPTION
- SWIR lens, also called near-infrared lens or short-wave near-infrared lens, is a fixed-focus lens whose working wavelength is mainly in near-infrared. The full name of SWIR is Short Wave infrared Radiation – short wave infrared. The general wavelength range is 800-2500nm, so SWIR lenses can also be understood as lenses with working wavelengths of 800-2500nm. Since the wavelength band of near-infrared cameras is generally 900-1700nm, some manufacturers also define SWIR lenses as lenses with an operating wavelength band of 900-1700nm.
- The SWIR lens series of HS Tech is optimized for the near-infrared band, with excellent resolution, high transmittance, compact appearance, and easy use. Among them, the 25.6mm SWIR short-wave near-infrared lens has an imaging size of up to 25.6mm and an operating wavelength of 800-1800nm; the 1″ SWIR short-wave near-infrared lens has an imaging size of up to 16.4mm and an operating wavelength of 700-1700nm.
