Measuring Power

Power measurements can be displayed in two ways:

³

absolute

³

relative

It is also possible to use a correction factor at specific wavelengths and to
add an offset value to your power measurement.

Displaying Absolute Power

When in absolute power, measured values are displayed in either dBm or
W units (pW, nW, μW, mW...) and the displayed value represents the
absolute optical power reaching the detector within specified uncertainty.
