The Soleil Babinet Compensator is basically a zero order waveplate with variable
retardation. Through a manual adjustment one may select a uniform phase difference
between the e- and o-rays of 0 to 2π.
As a result, incident elliptically or circularly polarized light can be converted
to linearly polarized light by introducing the appropriate compensation. From
readings obtained, a complete analysis of the state of polarization of incident
light can be made. Of course, the converse of this is also true, that is, any
desired polarization form can be obtained by pre-setting the appropriate values
on the instrument.
Digital Micrometer Drive Provides 0-360º
Retardation
Self-Calibrating
The above listed features are available only with Special Optics Compensators. Precision
and operational convenience are provided by the unique indexing head with eight
detents spaced at 45º intervals for rapid and accurate orientation of the
crystal's axes. A 0º to 360º precision engraved drum with vernier
provides added versatility. For all compensators mounted on the Model 60-1026
Rotary Mount, the distance from the mounting base to the optical centerline is
76.2mm. Four 1/4"-20 clearance holes for mounting are spaced 50.8 mm along
the beam propagation axis and 50.8 mm orthogonal to the propagation axis. All
compensators are supplied in wood instrument cases with instruction manual.
