Flexible power detectors with high damage threshold
Modular power detectors for precise laser measurement
UP power detectors are extremely versatile. They were developed for measuring medium and high laser power and are suitable for both continuous wave and pulsed lasers. With their modular design, the numerous product variations can be flexibly adapted to different applications. For example, different absorber coatings and cooling types ensure that the devices can be optimally matched to the beam profile, power, and wavelength. Thanks to their robust thermopile technology, they are particularly durable and reliable.
High damage thresholds and flexible cooling options
Depending on the model, UP detectors measure medium power ranging from a few watts up to 2.5 kW. The versions with “W coating” achieve damage thresholds of up to 100 kW/cm² and are ideal for highly focused beams in the UV and IR range (except CO₂ lasers). For applications with extremely high energy and power densities, the UP-QED series offers the highest damage threshold on the market thanks to a proprietary absorber at wavelengths between 300 nm and 2.5 µm. Depending on the application, different aperture sizes, absorber thicknesses, and cooling concepts (convection, heat sink, fan, and water) are available.
