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 find 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 profile 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 highly accurate power meter also needs to be independent from external influences such as laser position and diameter. This is why PRIMES relies on the calorimetric principle for all power meters. Despite being the most accurate and linear measuring principle by far, there is still room for improvement.
Reliable, precise and now even more robust due to its novel ultrasonic flow meter (for models CPM F-10 and CPM F-30). By replacing the conventional flow meter with a new ultrasonic version, any potential interference from a wearing part is eliminated, making it even more reliable and easier to maintain in the long term.
This is why the CompactPowerMonitor CPM+ is the ideal choice for all laser power measurements, not only under ideal laboratory conditions, but also in harsh industrial environments.
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 long term tests running for hours or even days. Combined with a fiber receiver it can even measure the power output of fiber guided lasers directly out of the fiber.
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.
