Many applications do not require “long term” power monitoring, but it is sufficient to have readings in a snapshot just to monitor if the power level is okay, as there is no necessity to measure over an extended period of time the laser power stability; moreover, many times water is not available on the laser machines, so service operations are easier if the measurement instrument do not require water cooling: that’s the world for a different class of instruments known as “Power Probes”.
These instruments are stand-alone meters made of a thermal probe connected to electronics with its display. In general, instruments of this type are thermometers that measure a temperature difference in a fixed time and have a simple digital display. FIT and CRONOS have been ergonomically designed in all their details, such as the LCD display and the balance of weights, to provide a comfortable and safe operation.
LaserPoint has introduced a real breakthrough in the field with two series of fully automatic laser power probes that calculate laser power by a microprocessor based measurement of temperature dynamics. Their measurement and acquisition technique self-determines the time needed to carry out a measurement: data acquisition is triggered and stopped by detecting set heat parameters thresholds.
The absorbers feature low reflections and high damage thresholds; in particular the hi-power, multi kilowatt CRONOS have a concave conical shape to avoid dangerous back-reflections toward the operator.
