High performance image conversion IR viewers (handhelds) used to observe indirect radiation of infrared light sources with wide spectral range 350 – 2000 nm
Infrared viewers focus emitted or reflected light into the image tube where electron image is generated. When powered (battery or power supply), a 16-18 kV voltage is generated to accelerate the electron image into the output phosphor screen. The fluorescent green light output (550 nm) is observed via an adjustable eyepiece lens.
