The CompactPowerMonitors CPM+ are a family of power meters ranging from the ’small’ CPM+ F-1 (max. 1.4 kW) to the CPM+ F-30 with a capacity of up to 30 kW. All of them feature the calorimetric measuring principle, making the readings stable and precise, especially making them independent of beam size and position. The good accuracy of ± 3 % is a ‘no footnote’ value – there are no additional / hidden contributions as you might fi nd in some data sheets (+ x % of scale, + y % of linearity, + z % for the readout device). The CPM+ can be used as a stand-alone power meter, providing the information you need on its integrated display. When using it with our new LaserDiagnosticsSoftware LDS, data storage,
processing and analysis come at the click of your mouse. And of course, the parallel operation of a focus analyzing device like the FocusMonitor or BeamMonitor works seamlessly, combining your power readings with your laser profi le data.
Your benefit
Lasers for NIR, green or blue – the CPM+ with its advanced absorber can measure them all. Due to the special surface structure in combination with the industry proven coating, it generates very low back reflection. An additional benefit is the compact size and low weight for a water-cooled instrument that can be used as a permanent absorber for high powers.
Tech Corner
We believe that a power meter should be independent of the diameter and the position of the laser beam. This is why PRIMES relies on the calorimeter technology to build power meters. As just the amount of generated heat is counted, this technology is not affected by other laser parameters. No matter what the beam diameter or position is, the CPM+ will always show a correct and stable reading for the laser power.
This is why the CompactPowerMonitor is the ideal choice for all laser power measurements, not only under ideal conditions in a laboratory, but also in a harsh industrial environment where positions and diameters and other parameters might vary.
It is surprisingly compact for a device with such a large power range. It can be used as a permanent absorber, excellent not only for service tasks, but also for burn-in tests running for hours or days. The built-in interlock connector ensures safety when running the device inside a cabin where there is a distance between the operator and the device.
The CPM+ features an advanced absorber that combines a proven surface structure with our optimized coating, resulting in a virtually fl at response for all industrial laser wavelengths from blue to green to NIR. You don’t even have to fiddle with setting a wavelength, you just go ahead and measure the laser power.
Conclusion
Improve your power measurements by using the PRIMES calorimetric technology. The CPM+ is the most reliable and precise tool to cover all requirements of a service technician and laser user.
