1.2.3 High Energy Pyroelectric Sensors 10µJ to 40J Features ֺ ֺ Removable diffusers ֺ ֺ PE50-DIF-ER-C mainly for NIR lasers ֺ ֺ PE100BF-DIF-C for very large beams ֺ ֺ Rep rates up to 10kHz ֺ ֺ Measure lasers with pulse widths up to 20ms Very large aperture Diffuser Aperture mm Absorber Type Spectral Range µm (a) Surface Reflectivity % approx.

For other settings, the spec is for >10% of full scale or greater than twice the "user threshold", whichever is greater. For use with StarBright, StarLite, Nova II, Vega or Juno. The sensors will operate with older Ophir meters and PC interfaces but do not support the threshold function and may give inaccurate readings with the diffuser in and therefore it is not recommended to use these sensors with older Ophir meters and PC interfaces. The user threshold feature allows adjustment of the internal threshold up to 25% of full scale if desired to avoid false triggering in noisy environments. For further information, see the FAQs on our Website. Notes: (c) With the Laserstar, Pulsar, USBI, Quasar and Nova/Orion with adapter only 2 of the 5 pulse width settings are available. For the PE50-DIF-ER-C, the 30µs and 1ms settings and for the PE100BF-DIF-C, the 1ms and 10ms settings. Furthermore, with the diffuser mounted, the sensor may saturate at lower than the maximum energy in some cases. Therefore it is recommended to use these sensors with the newer meters/PC interfaces.
