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.
