摘要：

We have measured the electrical and radiometric properties of a cryogenic bolometer/amplifier which is intended for use as a transfer standard in an infrared spectral comparator facility under development at the NIST. We have found its sensitivity to be approximately 20 pW, instability < 1 %, responsivity approximately 1,7 x 10(6) V/W, spatial nonuniformity < 1 % and nonlinearity < 1 % over five decades. These results show that this device can be used for its intended purpose as an IR detector transfer standard.
