The PD300 series has built in wavelength correction curves for measurements either with the
removable filter installed (filter-in) or removed (filter-out). These curves are stored in the sensor
EEROM. The correction curves, with a resolution of 1nm, ensure that the power reading is correct
at all laser wavelengths.
To simplify changing from one laser wavelength to another, the user can program up to 6 different
wavelengths to be available from the screen menu. Use the
procedure below to set the PD300 to
your laser wavelengths.
