What is the range of a SWIR camera?

Short-Wave Infrared (SWIR) cameras are portable imaging systems operating in the SWIR bandwidth with range from (1- 2.7) µm. This spectral range captures various images that are relevant for several regions of practice because there is lower autofluorescence and light scattering making it appropriate for in vivo imaging and other scientific works as well.

The range of SWIR cameras
Wavelength definition
The SWIR spectrum can be defined as transitions from that of near-infrared (NIR) to that of a midwave infrared (MWIR) region which includes ranges of approximately 1-2. 7 MICROM in the meters. This range is then classified into ranges of applications excepting none in- relation to the technology of realization.

Spectral sensitivities
SWIR cameras can exhibit spectral sensitivities extending from 400 NM to 2.2 mu m, thus some models are hyper and multi-spectral providing a wider area for imaging. This flexibility permits a thorough study of the specimens in question for a very great number of materials and conditions.

Spatial Resolutions
There is a wide variation in the spatial resolutions for the SWIR cameras, some models comes with a capability of achieving resolution of 5 micron and others having much poorer resolution. Such a degree of resolution is necessary in the applications for example industrial inspection and machine vision where accurate pictures must invariably be captured.

Applications of SWIR cameras
Industrial and scientific research
SWIR cameras find applications in industrial and scientific processes such as material examination, environmental surveys, and medical imaging. Because of their unique abilities to see through some materials and operate under low lighting conditions, these cameras have become must-have tools for scientists and designers.

Security and surveillance
In the security aspect, SWIR thermal cameras improve the power of surveillance systems by enhancing the imaging capability under low visibility conditions. They are also integrated into facial databases for quicker and less reliable recognition that uses their detailed images.

The optical range of the SWIR cameras is not only limited to its wavelength as the features such as spatial resolution and spectral response also come into play in the broad range of applications of the camera across different industries. Sinoseen, who is camera module manufacturer, does customization of the devices in order to satisfy each client’s requirement bearing in mind that SWIR technology has potential in every application undertaken.
