Profile: Macken Instruments, Inc. is a provider of calorimeters. Our power probes are calorimeter-type power meters which measure laser power using a timed exposure. They are self-contained units consisting of an absorbing head, a temperature measuring mechanism, a zeroing knob, & a readout dial. Our digital laser power probe consists of microprocessor-based digital meter and probe head. Our thermal image plate displays IR laser beam through the use of thermal-sensitive phosphors. Our spectrum analyzer can be used as a monochrometer, with external detectors mounted to monitor individual lines, and the display screen is removed to allow the light to pass onto the detector.
