INFRARED VIEWER ABRIS-M series
High performance image conversion viewers are designed for viewing, recording and digitization of radiation emitted by ultraviolet and infrared sources in the 270…2000 nm spectral range and are ideal for a wide field of applications involving laser beam alignment and inspection, optical fiber alignment, telecommunications, photo processing, surveillance and investigation in botany, biophysics, medicine, forensics and art restoration, examine documents, records, engravings, paintings, infrared microscopy, infrared luminescence (by ultraviolet stimulation), fluorescence.
How infrared viewer works.
Infrared viewer works by focusing the infrared light reflected by or emitted from a selected subject onto the image tube. An electronic image is generated on the image tube screen in accordance with the radiation intensity and the S-1 spectral sensitivity of the photocathode material. The unit is powered from one CR123, 3V battery or one 16340, 3.7V rechargeable battery and from external power 5V with interface USB-C.
