DESCRIPTION
Digital thermal imaging scopes Quantum based on IR sensor (uncooled 
microbolometer)  are  represented  by  a  number  of  models  featuring 
various frame rate, magnification and lens diameter. The scopes are 
designed for the use both in the nighttime and in the daylight in inclement 
weather conditions (fog, smog, rain) to see through obstacles hindering 
detection of targets (branches, tallgrass, thick bushes etc.). Unlike the 
image  intensifier  tube  based  night  vision  devices,  thermal  imaging 
scopes Quantum do not require an external source of light and are not 
affected by bright light exposure. 
The  Quantum  XD  series  features  stadiametric  rangefinder,  multiple 
color modes and 50 Hz frame rate. 
Thermal  imaging  scopes  Quantum  have  a  wide  range  application 
including night hunting, observation and terrain orientation, search and 
rescue operations.
