Description:
The PE50-DIF-ER-C is a pyroelectric energy meter with a removable diffuser for high energy YAG and erbium lasers. It has a 46mm aperture with diffuser out and 33mm aperture with diffuser in. It can measure energies from 10µJ up to 30J. It can operate at repetition rates up to 10kHz and is calibrated for 1.064, 0.532, 2.1 and 2.94µm. The sensor comes with a standard 1.5 meter cable for connecting to a meter or PC interface.

Notes: (a)
Calibrated at 532nm and 1064nm only
Calibrated at 1064nm,2100nm and 2940nm
Notes: (b) With the "user threshold" setting set to minimum. For other settings, the spec is for >10% of full scale or greater than twice the "user threshold", whichever is greater. For use with Centauri, StarBright, StarLite, Nova II, Vega, Juno, Juno+ and EA-1. 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.
