ScienTECH Vector Series - Detector Operating Parameters

PN 10795T 3
DETECTOR OPERATING PARAMETERS
All detectors are calibrated at a specific wavelength and the detector’s operating parameters are derived
for that wavelength. This information is recorded below and on the detector’s serial tag. When a detector
is used at a wavelength other than the calibration wavelength some of the operating parameters may need
to be adjusted. For specific instructions please refer to the Operating Procedures section for the type of
detector you are using.

The V/J is used to calibrate the power meter to a known NIST traceable standard. This is the value the
meter must use.
The V/J (Scope) is the “true” Volts per Joule as seen at an oscilloscope.
