ABRIS M Viewers
Spectral region is 350 – 2000 nm;
Better resolution (60Lp/mm) and higher-sensitivity (up to 2 times better) compared with other IR viewers;
Hand-held / post mounted;
Battery + DC powered;
Up to 35 hours continuous working;
Pulsed and CW light detection without synchronization;
Connect to PC via video adapter;
Laser alignment and safety
(IR) Infrared viewer is ideal for alignment of infrared laser beam and optical components in near infrared systems.
With a microscope adapter IR viewer can be used to view through the surface of silicon and gallium arsenide wafers.
Forensics and art restoration
High performance image conversion IR viewers are based on high-grade image converter and designed to observe indirect radiation of infrared laser, light emitting diodes (LED), dye and other IR-sources in 350 – 2000 nm spectral range.
(IR) Infrared viewer is based on a first generation high-grade image converter that has an electro-static focusing system, photocathode S-1+ with increased concentration of oxygen and screen of type P-20 with maximum of luminescence at 550nm.
Infrared viewer focus emitted or reflected light from a chosen subject into the image tube where electron image is generated. When powered (with battery or power supply) the 16-19 kV voltage is generated required to accelerate the electron image into the output phosphor screen. The fluorescent green light output (550 nm) is observed via an adjustable eyepiece lens.
