Overview of the
Exicor 150AT Birefringence
Measurement System
The Exicor 150AT birefringence measurement system is an easy-to-use highly
sensitive instrument for measuring the fast axis orientation and low-level magnitude
of linear birefringence in flat, parallel-surface optical materials. The system can also
give an estimation of the differential stress present inside the sample (optional). An
automated X-Y stage is used to move the sample in order to measure different
locations to create a “map” of these measurements.

Description
Listed below are the main components of the Exicor 150AT Birefringence
Measurement System. See figure 1.1 on page 12.
•
System Scanning Module:
Includes the components for generating the
modulated beam of light and detecting the light as it exits the sample. The
individual components are:
-
He-Ne Laser – provides 633nm beam source.
-
50 kHz PEM – provides controlled modulation of the beam polarization
state.
-
60 kHz PEM – provides controlled modulation of the beam polarization
state.
-
Detector – one DET200 Detector for measurement of the beam
polarization states. Signals from the detectors are used to determine the
retardation (birefringence) and fast axis angular orientation of the sample
under study.
