Light with a wavelength between 900 and 2500 nm is referred to as SWIR. SWIR imaging requires sensors and camera parts that can operate in the shortwave infrared spectrum, which is beyond the upper limit of silicon as ordinary silicon sensors have an upper limit of roughly 1000 nm.
SWIR technology is used in military applications because it allows cameras to “see through” haze, mist, rain, fog, and other difficult atmospheric conditions while producing images with increased contrast.
The Short Wave Infrared (SWIR) spectrum includes wavelengths between 900 and 1700 nm. In contrast to thermal images, which rely on emitted photons, SWIR is analogous to visible light in that photons are reflected or absorbed by an object, giving the strong contrast required for higher resolution imaging.
Using radiation from the portion of the electromagnetic spectrum that is invisible to the human eye, short-wave infrared imaging (SWIR) is a sophisticated approach for creating images.
In addition to electronic board inspection, solar cell inspection, product inspection, identification and sorting, surveillance, anti-counterfeiting, and process quality control, SWIR imaging is employed in a wide range of other applications as well.
The Global SWIR camera market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The Ninox 640 SU, the world’s best “scientific” SWIR camera, is introduced by Raptor. The Ninox 640 SU, a vacuum-cooled InGaAs-based camera with a 640512 sensor and the maximum possible spatial resolution (15 m x 15 m pixel pitch), has been released by Raptor Photonics.
For extremely long exposures of up to 5 minutes, the Ninox 640SU is vacuum-cooled to -80°C. It is the greatest “scientific” SWIR camera available right now thanks to its extremely low dark current and read-noise.
For starting applications in SWIR wavelengths (from 900 nm to 1700 nm), such as NIR-II In-Vivo Imaging, Fluorescence Imaging, and Astronomy, it is the ideal camera. The Ninox Ultra is one of the most sensitive SWIR cameras available on the market and is ideal for imaging weak signals with longer exposure times.
It combines a low read noise of 40e- in high gain and a dark current reading of 300e/p/s at -80°C. With a 15 m by 15 m pixel pitch, it has a resolution of 640 512. In addition, the camera provides a high intra-scene dynamic range of 56dB in high gain, allowing for the simultaneous capturing of bright and dark areas of a scene.
The C-RED family of SWIR cameras are extremely quick and low noise, operating at 600 frames per second with less than 60 electron readout noise.
In order to do this, a high resolution 640 x 512 InGaAs PIN photodiode detector with a 15 m pixel pitch and an electronic shutter with integration pulses under 5 s is incorporated.
The C-RED 2 opens up new opportunities for science, research, and business. It was created for high-end SWIR applications in low light. With an expanded wavelength (from 1.4 to 2.0 m) and a quantum efficiency of over 70%, the C-RED 2 ER enables even deeper infrared and creates new opportunities for astronomy, the life sciences, and business.
The C-RED 3 is thought to be the quickest uncooled VGA camera for SWIR imaging and was created specifically for short exposure times. The autonomous, little C-RED 3 is also offered in OEM form.
