DEVICE TO MEASURE ABSORBING AND RADIATING CAPACITIES OF THIN-FILM SAMPLE Russian patent published in 2014 - IPC G01K17/08 

Abstract RU 2535648 C1

FIELD: measurement equipment.

SUBSTANCE: device to measure absorbing and radiating capacities of a thin-film sample comprises a cryostat, a flat sample and a flat absorber installed in parallel at a certain distance from each other, two sensors, temperature meters and a source of power connected to a heater of an absorber or a sample with measurement of absorbing or radiating capacity. The absorber and the sample contain a thin-film thermometer of resistance and a heater isolated from each other by a dielectric layer and distributed along the area of the absorber and the sample. The total heat capacity of the resistance thermometer and the heater is less than heat capacity of the sample and the absorber. The absorber has heat capacity equal to or less than sample heat capacity, and the source of power is a generator of an alternating signal.

EFFECT: increased accuracy and sensitivity of a device when measuring absorbing and radiating capacities of a thin-film sample.
