Description:
The PE9-ES-C is a pyroelectric energy meter for very low energies with an 8mm aperture. It can measure energies from <0.05uJ up to 200uJ. 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.
0.193, 0.355, 1.064, 1.48-1.6 240-800nm add ±4%,
2-3µm add ±8%, 10.6µm add ±15%.

Note: (b) For >7% (>10% for PE9-ES-C) of full scale, with the "user threshold" setting set to minimum. For other settings, the spec is for >7%/>10%
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: (c) With the LaserStar, Pulsar, USBI, Quasar and Nova/Orion with adapter, only 2 out of 3 pulse widths settings are available; the 1µs
(displayed as “10µs”) and the 2µs (displayed as “20µs”).
