Custom Calibration
The calibration setup window allows the user to select the polarimeter calibration matrix to
be used for SOP measurement.
Factory Matrix: The POD-201 or PSY-201 comes with a set of factory-generated calibration
matrices for wavelengths in its operating wavelength range. If “Factory Matrix” is
selected, then the wavelength setting determines the built-in calibration matrix
that is used for measurement. Factory matrices are spaced at 5 nm intervals for
1550nm instruments and at 2nm intervals for 1310nm instruments.
Custom Matrix: If this option is selected, the user can load a user-generated calibration
matrix to use for measurement.
Matrix Calibration: Use this function to generate a new calibration matrix for the current
operating conditions (wavelength, temperature). Such a calibration matrix can
yield more precise results under particular operating conditions, or can be used to
generate calibration matrices for wavelengths outside of the instrument’s nominal
operating range, although the measurement performance may not be as good as
for wavelengths in the range.
To generate a new matrix, type the light source wavelength into the “Wavelength” box,
and click “Calibrate”.
