PRIMES PowerMeasuringModule (PMM) is the established standard for measuring high power lasers in industrial processes. It is designed for fast and reliable quality assurance in a rough and highly synchronised environment. Thanks to its standardised interfaces it is easy to integrate and delivers highly accurate measurement results directly to the plant. By using the well-known calorimetric principle, extremely fast measurements within 3 seconds are possible. Enough for a qualification e.g. during a part exchange in a production line.
