• 0.2- to 20-μm spectral range
• 20- to 1000-W measurement range
The battery-operated Comet 1K laser power meter from Rofin-Baasel UK Ltd. can be set to automatic mode for hands-free operation. As soon as a laser is switched on, the probe measures the heat rise from a 10-s exposure to the laser beam and calculates the power with ±5% accuracy by comparing the first and final temperatures. A sophisticated algorithm takes into account the initial temperature of the meter to ensure accuracy of measurement, even if the instrument already is hot, and it enables several sequential readings to be taken before the device must be water-cooled. The device’s readable spectral range is 0.2 to 20 μm, and its power measurement range is 20 to 1000 W. The display is a 2 × 8-character LCD with a character height of 5 mm. Internal memory stores the last three readings.
