Digital version of IR viewer (DIG series) is based on multiphoton absorption (MPA) phenomenon when the wavelength of the laser exceeds the linear spectral detection range of the silicon material. In addition, the process of photoelectrons requires spatial and temporal filtering from noise to enhance the visualization of IR photons beyond the 1,1µm spectrum. By adjusting the gain on a pixel-by-pixel basis, it is possible to achieve imaging up to 1,7µm.
High performance image conversion infrared viewers (IC series) based on highgrade image converter are designed to observe indirect radiation of infrared laser, light emitting diodes (LED), dye and other IR-sources in 350–2000 nm spectral range. Infrared viewer is based on a first-generation high-grade image converter that has an electro-static focusing system, photocathode S-1+ with an increased concentration of oxygen and screen of type P-20 with the maximum of luminescence at 550 nm. Infrared viewer focus emitted or reflected light from a chosen object into the image tube where the electron image is generated. When powered the 16-18 kV voltage is generated to accelerate the electron image towards the phosphor screen at the output. The fluorescent green light output (550 nm) is observed via an adjustable eyepiece lens.
