PE80BF-DIF-C
P/N7Z02954
Description:
The PE80BF-DIF-C is a pyroelectric energy meter with a diffuser for concentrated beams. It has a 67mm aperture and can measure energies from 4mJ up to 40J. It can operate at repetition rates up to 250Hz and covers the spectral range from 0.19 - 2.2, 2.94µm. The sensor comes with a standard 1.5 meter cable for connecting to a meter or PC interface.

Notes: (a) Calibration accuracy at various wavelengths as specified here. At other wavelengths, there may be an additional error up to the
value given.Specified wavelengths:355nm, 532nm, 1064nm, 2100nm and 2940nm.Max additional error at other wavelengths not specified above: ±2%. <250nm not calibrated.
Notes: (b) For wavelengths >2.1μm, derate to 10% of above values. For wavelengths below 600nm, derate to 60% of given values.
For wavelengths below 240nm, derate to 1J/cm². For beam size ≤16mm. For 32mm beam, derate to 50% of above values.
Notes: (c) 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. 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.
Notes: (d) With the LaserStar, Pulsar, USBI, Quasar and Nova/Orion with adapter only 2 of the pulse width settings are available, the 1ms and 10ms settings.
Notes: (e) For maximum power. For lower powers the damage threshold is correspondingly higher.
Notes: (f) For powers below 50W it is recommended to work with the fan off. If working with the fan on, the threshold must be set to 6% and the lowest measurable energies will be as follows:
