Description

The proper calibration of an optical power meter requires the
verification of two critical parameters: absolute accuracy at a
given reference power over a wavelength range and linearity at a
given wavelength over a power range. We discuss the key elements
involved in determining the uncertainty in the absolute accuracy
and the non-linearity of the power response under what are termed
"reference conditions of calibration". We also discuss the
underlying causes of erroneous measurements resulting from each of
the three subsystems constituting a power meter: detector element,
collecting optics and electronics.
