SWIR Short Wave Infrared 900~1700nm (0.9 to 1.7 microns) See Through Haze/Fog Long Range Surveillance
SWIR is an acronym for Short Wave InfraRed. It refers to the wavelengths from 0.9 to 1.7 microns.
The main advantages of using SWIR technology in military applications is that SWIR cameras often “see through” and generate high contrast images in adverse environments. Especially compared to visible images through challenging weather conditions.
Conditions such as Fog, Haze, Rain and Dust are all penetrated by SWIR Imaging due to the reduced Rayleigh scattering of the longer wavelengths it utilizes when compared to visible imaging.
The short-wave infrared (SWIR) portion of the spectrum offers unique capabilities, often complementary to LWIR and MWIR imaging. Imaging in SWIR uses reflected light, much like the slightly shorter wavelengths of the visible spectrum.
Many SWIR systems are marketed as low light or as good camera systems for complete darkness. This isn't always the case (such as with long range). Since, unlike MWIR and LWIR, SWIR imaging does not depend on the intrinsic black body emissivity of target objects, therefore it is usually not referred to as a form of thermal imaging. This means that SWIR requires illumination in long range scenarios.
Infiniti is currently developing an effective Long Range SWIR Illuminator for such applications.
Infiniti optics provides a wide variety of EO/IR camera solutions all the way from a component level, open frame modules (lens and sensor attached) or as complete integrated PTZ cameras with Visible and SWIR sensors for ultra long range imaging required by a host of military and defense applications.
