Abstract:
A SPECTROPOLARIMETER HAVING A CONTROL UNIT FOR SUBSTANTIALLY ELIMINATING ERRORS THAT WOULD OTHERWISE OCCUR IN
THE MEASUREMENT FROM ONE WAVELENGTH TO ANOTHER AND FROM ONE SPECIMEN TO ANOTHER. THE CONTROL UNIT INCLUDES A ZERO-CORRECTION SUB-UNIT, A DEFLECTION SIGNAL SUB-UNIT AND A BALANCING SUB-UNIT. THE ZERO-CORRECTION SUB-UNIT MAKES SUCH ZERO-CORRECTION POSSIBLE THROUGHOUT THE ENTIRE SPECTRUM. THE BALANCING SUB-UNIT MAKES IT POSSIBLE TO SHIFT THE ZERO LEVEL TO FACILITATE RECORDING ON AN ENLARGED SCALE THE SIGNIFICANT DATA OF A SPECTROPOLAROGRAM. THE BALANCING SUB-UNIT ALSO MAKES IT POSSIBLE TO RECORD DIFFERENT SPECTROPOLAROGRAMS AND EVEN DIFFERENT PARTS OF THE SAME POLAROGRAM TO DIFFERENT SCALES.
