Product Description
The SM-3R infrared viewer is discontinued from 2019 December.
The SM-3R is a miniature infrared viewer that fits comfortably in the palm of a hand or on a face-mask for hands free operation. This viewer is suitable when size and weight are more important.
How infrared viewer works?
IR 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 16-18 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.
Typical applications
- Laser alignment and safety
(IR) Infrared viewer is ideal for alignment of infrared laser beam and optical components in near infrared systems. - Semiconductors inspection
With a microscope adapter IR viewer can be used to view through the surface of silicon and gallium arsenide wafers. - Forensics and art restoration
- Photo processing
- Thermal imaging
