With repetition rates to 10 kHz, PE50-DIF-ER-C offers energy measurement down to 100 µJ and has diffuser for high damage thresholds up to 20 J/cm² for 300 µs pulses. PE50BB-DIF-C, with flat broadband coating, measures energies down to 0.1 mJ and has flat spectral response from 0.19–20 µm with diffuser removed. With diffuser, sensor supports energy densities up to 3 J/cm² for nanosecond pulses. Both have active aperture areas to 46 mm and user-adjustable threshold that prevents false readings.
