METHOD AND DEVICE FOR THERMOACCUMULATION OF HEAT (COLD) AT CONVEYING OF OPTICAL INSTRUMENT IN THERMOCAPPING FROM THERMOCHAMBER TO OPTICAL BENCH Russian patent published in 2001 - IPC

FIELD: check-up of equipment with an optical guidance system, in particular, guidance instrument sight. SUBSTANCE: prior to the effect of the heat (cold) accumulator, the instrument is covered with a non-polar film with a high transparency, placed in the thermocapping, and a heat (cold) accumulation screen is installed between the optical instrument and the heat insulation of the thermocapping, that is made of heat accumulating metal, after that the thermocapping with an open cover is placed in the thermochamber of heat (cold) accumulation, seasoned for a time for comparison of the temperature of the instrument mechanisms parts with the environment, then the instrument mechanisms are checked for functioning at a preset temperature, after that it is extracted from the thermochamber, the cover is closed, and conveyed to the optical bench. The above method of check-up of the optical instrument is accomplished by the device of heat thermoaccumulation at conveying of the instrument from the thermochamber to the optical bench, on which the optical mismatch of the information and sighting channels is determined. EFFECT: enhanced truth of measurement of optical mismatch of the information and sighting channels within the operating temperature of the optical instrument. 6 cl, 1 dwg
