Are you looking for a better imaging experience in terms of high resolution? Then, the SWIR imaging system is the best option. Find out from this piece.

SWIR Camera: The best for higher resolution imaging

Swir camera, also referred to as short-wave infrared, covers a wavelength range between 900 nm and 1700 nm. A human eye cannot see this wavelength; thus, you can use SWIR to achieve it. In addition, these cameras can give you clear images, at a long-range, in diverse surroundings like smoke, haze, mist, and fog, which hinder a bigger number of traditional visible cameras.

SWIR images taken from its spectrum are monochrome, but their properties are similar to visible light, like contrast and reflection. This offers an additional target identification capability to a multilayer surveillance platform. The imaging needs unique electrical and optical components for specific SWIR range performance.

In SWIR imaging and covering its range, InGaAs (indium, gallium, and arsenide) are the basic sensors used. Although you can commercially access line-scan linear InGaAs sensors, its area-scan sensors are regulated by ITAR. ITAR, which refers to International Treaty and Arms Regulations, is initiated by the government of the United States.

Products under the ITAR regulation should adhere to the strict exportation and import regulations to be made or sold in and out of the USA. With proper licensing, SWIR lenses can be used for several commercial applications.

Significance of SWIR

  • It gives clear images of even diverse weather conditions like haze, fog, and mist.
  • It does not require illumination.
  • It matches thermal cameras and can help during thermal cross-over scenarios.
  • It is a perfect option for effective identification.

Applications for SWIR

SWIR imaging is used in various areas such as;

  • Inspection of the electronic board
  • Identifying and sorting
  • Solar cell inspection
  • Surveillance
  • Produce inspection
  • Anti-counterfeiting
  • Quality control processing

SWIR is a clear definition of a specific wavelength range whereby electronic and optical components are designed and coated. This imaging system has more advantages than when used for quality control and inspection applications. To ensure the lowest irregularities and highest resolution, consider choosing components that have been specifically optimized, designed, and coated to fit within the range of SWIR.
