AXION KEY monoculars can be used for night-time hunting, observation and terrain orientation, and carrying out
rescue operations.
AXION KEY IR-matrix (microbolometer) based thermal imaging monoculars are represented by a number of
models that differ in magnification and lens diameter. These devices are designed for use both at night-time and
during the day in difficult weather conditions (fog, smog, rain), as well as where obstacles are present that
impede the detection of a target (branches, tall grass, dense shrubs etc.). Unlike night-vision devices that are
based on electron-optical converters, thermal vision monoculars do not require an external light source and are
resistant to the effects of bright light.

In low-temperature conditions, objects being observed (background) do, as a rule,
cool down to roughly the same temperature, because of which temperature contrast
is substantially reduced and image quality (detail) is poorer. This is a feature of
thermal imaging devices.
In positive temperature conditions, objects being observed (surroundings and
background) heat up differently because of thermal conductivity, thereby generating
a high temperature contrast. Accordingly, image quality produced by the device will
be higher.
