what is swir?Short-Wave Infrared (SWIR) light is typically defined as light in the 0.9 – 1.7µm wavelength range, but can also be classified from 0.7 – 2.5µm. Since silicon sensors have an upper limit of approximately 1.0µm, SWIR imaging requires unique components capable of performing in the SWIR range. Indium Gallium Arsenide (InGaAs) sensors are the primary sensors used in SWIR, covering the typical SWIR band, but can extend as low as 550nm to as high as 2.5µm. Although linear line-scan InGaAs sensors are commercially available, area scan InGaAs sensors are typically ITAR restricted, but are available for a number of commercial applications with proper licenses. SWIR imaging lenses are spe-cially designed, optimized, and anti-reflection coated for SWIR wavelengths.
why use swir?Unlike Mid-Wave Infrared (MWIR) and Long-Wave Infrared (LWIR) light, which is emitted from the object itself, SWIR is similar to visible light in that photons are reflected or absorbed by an object, providing the strong contrast need-ed for higher resolution imaging. Ambient star light and background radiance (nightglow) are natural emitters of SWIR and provide excellent illumination for outdoor, nighttime imaging.
It is essential to use a lens that is both designed and coated for the SWIR wavelength band. Using a lens designed for the visible spectrum will result in low resolution images and higher optical aberrations. Since SWIR wavelengths transmit through glass, lenses and other optical components (filters, windows, etc.) designed for SWIR can be manufactured using the same techniques used for visible components, decreasing manufacturing cost and enabling the use of protective windows and filters within a system.
A large number of applications that are difficult or impossible to perform using visible light are possible using SWIR. When imaging in SWIR, water vapor, fog, and certain materials such as silicon are transparent. Additionally, colors that appear almost identical in the visible may be easily differentiated using SWIR.
