Description:
The PE50BF-C is a high damage threshold pyroelectric energy meter with a 46mm aperture. It can measure energies from 120µJ up to 10J. It can operate at repetition rates up to 250Hz and covers the spectral range from 0.15 - 3, 10.6µm. The sensor comes with a standard 1.5 meter cable for connecting to a meter or PC interface.

Note: (a) Calibration curve is verified and adjusted at
specified wavelengths.
At other wavelengths, there may be an additional error
up to the value given.
Specified wavelengths: 248-266nm,
355nm and 1064nm.
Max additional error at 2940nm ±3%.
Max additional error at other wavelengths: ±2%.
<240nm not calibrated
Specified wavelengths: 193nm, 248-266nm,
355nm, 532nm and 1064nm.
Max additional error at 2940nm ±3%.
Max additional error at other wavelengths: ±2%.
Note: (b)
For wavelengths below 600nm, derate damage
threshold to 60% of given
values. Below 300nm, derate to 40% of given values.
Note: (c) 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 operatewith 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) With the LaserStar, Pulsar, USBI, Quasar and Nova/Orion with adapter, only 2 out of 5 pulse widths settings are available; for the PE50-C model the 2µs (displayed as “10µs”) and 1ms settings, and for thePE50BF-C model the 1ms and 10ms settings.
Note: (e) If the sensor is set to the 1064nm wavelength, then when measuring 10.6µm pulses, the reading will be approximately 1.19X the correct reading. If you use the attenuate function and set the attenuation toread 0.84, then you will have the correct reading at 10.6µm. The additional error at 10.6µm is +/-5%.
