Digital tactical thermal imaging device Archer TMA-55L/55M – new monoculars of TMA series. The device is equipped with a high-aperture lens with a manual focus and proximity sensors that much reduce the risk of disclosure.
The device is equipped with a highly sensitive passive receiver of a far infrared band (LWIR). ARCHER TMA-55L/55M has a built-in colour high-resolution microdisplay and an eyepiece with diopter adjustment.
Several set colour schemes allow choosing the necessary display option depending on the tasks performed.
An Archer TMA-55L/55M optical circuitry provides 2x optical magnification (using a detector with 640 х 512 resolution).
The device‘s display indicates operation modes, device status, and battery discharge. There are also modes of automatic and manual brightness and contrast control.
Archer TMA-55L/55M design comes in a shockproof, waterproof plastic housing with conveniently arranged controls. Power is supplied via 4 AA-type batteries (lithium or rechargeable batteries).
Due to the high-tech electronics unit, excellent functional capacities of the device are realized by minimal dimensions and power consumption.
