What is a CMOS-SWIR Sensor?

SWIR (Short-Wave Infrared) refers to the wavelength region of 900-2500nm. Traditional silicon sensors have an upper limit of approximately 1100nm. SWIR detection often requires camera components made of exotic materials. For example, Indium Gallium Arsenide (InGaAs) sensors (~900-1700nm range) are inherently expensive and often face challenges scaling to smaller pixel pitches and higher resolution arrays.

CMOS (Complementary Metal Oxide Semiconductor) is used in integrated circuits to to convert photons to electrons, in other terms what converts energy to create an image. A pure CMOS-based sensor is capable of SWIR wavelength detection without the use of expensive semiconductor materials, making it a cost-effective technology that enables seamless integration.

Added Image Data

SWIR extends imaging capabilities beyond what is visible to the naked eye-enabling image data to be captured in any light setting.
Higher Resolution + Contrast

SWIR's region of the light spectrum produces images with higher resolutions when compared to NIR and MWIR imagery.
Temperature Observation

Lower SWIR wavelengths nearing the mid-wave IR (MWIR) spectrum can capture energy emitted from objects (ability to provide thermal data).
Identification and Detection

Infrared absorbance, reflectance, and transmission can help identify and differentiate organic and inorganic materials.
Extended Visibility

SWIR sensors can detect smaller light photons making them less susceptible to scattering; penetrating through smoke, haze, or fog to produce a clearer image.
