11QE50 laser energy detectors can measure energy up to 85 J (with attenuator),
max repetition frequency - 4000 Hz. Low noise level - just 10 µJ. Effective aperture - 50 mm square.
These detectors are convenient to use and can measure relatively wide beams.
They are suitable for many OEM, manufacturing and laboratory applications.
