measure to
30mW or more without saturation. When the
additional filter is installed, the maximum power is on the
order of 300mW (or 3W with model PD300-3W). The
PD300 saturates when the output current exceeds 1.3mA
so the exact maximum power depends on the sensitivity
of the detector at the wavelength used. When saturated,
the legend "OVER" will appear on the screen. Table 2
gives the actual maximum power as a function of
wavelength.

Maximum Measurable Laser Power as a Function of Wavelength
5.2 Setting up the PD300 to display the user's chosen
wavelengths
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.
In order 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.
Please use the following
procedure to set the PD300 to
your laser wavelengths.
