Pyroelectric Energy Sensors
Description:
The PE10-C is a pyroelectric energy meter for low energies with a 10mm aperture. It can measure energies from 1µJ up to 10mJ. It can operate at repetition rates up to 25kHz and covers the spectral range from 0.15 - 12µm. The sensor comes with a standard 1.5 meter cable for connecting to a meter or PC interface.

Note: (a) Calibrated curve is checked and adjusted at the
following wavelengths (µm)
For other wavelengths in the curve there is additional
calibration error as stated.

Note: (b) For wavelengths below 600nm, derate damage threshold to 60% of given values. Below 300nm, derate to 40% of given values.
Note: (c) For >7% of full scale, with the "user threshold" setting set to minimum. For other settings, the spec is for >7% of full scale or greater than twice the "user threshold", whichever is greater.
The user threshold is not available with LaserStar, Nova/Orion, Pulsar, USBI and Quasar. For these meters, the threshold is set to minimum and the linearity spec is >10% of full scale. The PE-C series will only operate
with Nova or Orion meters with an additional adapter Ophir P/N 7Z08272 (see page 105). The adapter can introduce up to 1% additional measurement error.
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.
Note: (d) The absorption at 675nm is approximately the same as at 10.6µm. Therefore, to measure a CO2 laser, set to the 675nm setting. The additional error for measuring 10.6µm is ±5%.
Note: (e) With the LaserStar, Pulsar, USBI, Quasar and Nova/Orion with adapter, for the PE10-C model the 1µs pulse width setting is displayed as “10µs”.
