FIELD: instrument making.
SUBSTANCE: invention relates to optical instrument-making and can be used in multichannel optical-location laser systems, operating under high humidity and temperature drops. Essence is that mirror has a substrate (1) of optical material, mirror coating (4) and two current-conducting layers (2, 3). Besides, one current-conducting layer (2) is put between the substrate (1) and mirror coating (4), and the other current-conducting layer (3) is made on the rear side of the substrate (1). Both current-conducting layers (2, 3) are connected to the voltage source through a current-conducting bus (7), arranged on the end surface of substrate (1). Mirror coating (4) and second current-conducting layer (3) are equipped with protective dielectric films (5, 6), optical thickness of which is equal to half of the wavelength of a multipath radiation.
EFFECT: technical result is beam strength increase, evenness and rate of heating, simplified manufacturing.
