Thermal front attachments are used paired with a daylight optical sight and are mounted in front of the sight’s objective lens. The main purpose of a thermal attachment is shooting at night or in terms of fog, light rain, snow or a smoke screen. Attachments work in passive mode using the infrared emission of objects and landscape. They do not need any additional illumination. BUT they limit or deprive the ability to see through the glass, water, heavy rain or heavy snowfall.
Our thermal attachments use microbolometers with shutterless calibration technology, which allows quick startup and constant viewing without stoppages or delays. The specially developed electronic control system makes no need for a complicated menu.
