Infrared (IR) viewers are used to observe, register, and record both indirect and direct radiation of IR lasers, light-emitting diodes (LED’s), dye, and other IR-sources. It is ideal for IR-laser beam alignment and inspection, optical fiber alignment, telecommunications, solar panel inspection, photo processing, surveillance and investigation in botany, biophysics, medicine, forensics and art restoration, infrared microscopy, fluorescence, etc.

Digital version of IR viewer is based on multiphoton absorption (MPA) phenomenon when the wavelength of the laser exceeds the linear spectral detection range of the silicon material. In traditional applications, the usable spectrum of CMOS image sensors is limited to wavelengths below 1100 nm where linear or single-photon absorption (SPA) occurs. In this case, one photon has sufficient energy to excite an electron from a valence band to the conduction band, which results in a detectable signal in an image sensor. For wavelengths above 1150 nm, photons are not absorbed, and silicon is transparent. However, if photons with an energy above half of the bandgap energy interact with the same electron within a short enough time window, with specific threshold of light intensity can be sufficient to excite an electron into the conduction band. Besides that, the process of photoelectrons requires spatial and temporal filtering from the noise necessary to enhance visualization of IR photons beyond 1,1µm spectrum. In this way by adjusting gain pixel by pixel basis it is possible to achieve imaging up to 1,7µm.
