PIRA Classification: 6H30.80
Description: A linearly polarized laser beam is directed through a solenoid containing a glass sample. Upon exiting the solenoid, the beam passes through a polarizer and shines on a photodetector (the output of which is connected to a multimeter). When current is sent through the coil, the plane of polarization of the laser is rotated by a few degrees. To determine the amount of rotation, the analyzer is rotated until the output of the detector returns to its original value.
Special Instructions: Apply no more than 3 amps to the coil. The plane of polarization should rotate by 5 degrees at 3 amps. The Verdet constant of the sample is 23 radians/Tesla meter.
Condition: Ok
Setup time: 2 minutes
Safety Issues: None
