A method and apparatus for measuring and adjusting output of a heat lamp for an optical TLD reader includes an optical system which matches the optical system of the TLD reader, means for supporting a heat lamp to be calibrated, and an element plate having at least one heat absorbing substrate supported in alignment with the optical system. The heat lamp is electrically connected to a lamp driver circuit of the TLD reader, and a thermocouple is mounted in thermal contact with the heat absorbing substrate. In use, the lamp driver circuit of the TLD reader drives the heat lamp mounted in the calibration and adjusting device. This device monitors the signal generated by the thermocouple and displays this signal as a measured heat response curve. This measured heat response curve can be compared with a 'standard' or reference heat response curve to determine whether the lamp driver circuit has been adjusted properly for the heat lamp being tested, and to determine the nature of any required adjustments.
