1 General Information
Thorlabs polarimeters are terminating, wave-plate-based modules for free-space and - with in-
stalled fiber collimator - fiber-based measurements of the state of polarization (SOP). Their high
dynamic range of 70 dB, three models covering the visible to near-infrared range, and accuracy
of ±0.25° on the Poincaré sphere opens a wide spectrum of application possibilities.
Each measurement sensor is calibrated at different wavelength points. These base points are
interpolated.
The PAX1000 is basically powered via the USB port. For a measurement speed higher that 50
samples per second, an additional power supply is required - please connect the DS15 power
supply to your mains outlet and to the PAX1000.
Note
Polarization measurements with the PAX1000 are possible only for monochromatic coherent
light (e.g., laser emission)!
