5.2 Optical Power Calibration and Wavelength Sensitivity Correction

Features of sensor photodiodes include varying sensitivity for individual photodiodes and wavelength-

dependent sensitivity. This instrument ensures accuracy over a wide range of wavelengths by combining the

power calibration at the calibration wavelength and the wavelength sensitivity correction over a wide range

of wavelengths. The calibration wavelength can be traced to national standards, ensuring high accuracy.
