11QE95 laser energy detectors can measure energy up to 250 J (with attenuator). Low noise level - just 15 µJ. Large effective aperture - 95 mm square. These detectors are convenient to use and can measure relatively wide beams. They are suitable for many OEM, manufacturing and laboratory applications. Specifications
