For other wavelengths in the curve there is additional
calibration error as stated.
Note: (b) On lowest scale, offset can reach -100nJ for frequencies below 5kHz.
Note: (c) For >10% of full scale.
Note: (d) For wavelenghts below 600nm, derate damage threshold to 60% of given values. Below 300nm, derate to 40% of given values.
Note: (e) 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 available with Nova II, Vega or Juno. For other 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 74).
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. The user threshold setting represents
the approximate minimum energy for pulse widths below ~50% of the pulse width setting. For longer pulse widths, the actual minimum may be higher. For highest accuracy, it is
recommended to zero the sensor against the meter the first time it is used with a particular meter. For further information, see the FAQs on our Website.
Note: (f ) A shock absorbing mounting post is available for situations in which sensor is mounted on a surface subject to shock or vibration. This can prevent false triggering and allow working
at lower minimum energies (see accessory page 74 for mounting post).
Note: (g) The 3000nm setting is calibrated for 10.6µm as well. To measure CO2 laser, set to the 3000nm setting. The additional error for measuring 10.6µm is ±5%.
Note: (h) Add 3% to error for wavelengths >2µm.
