The BSC Babinet Soleil Compensator is constructed from two opposed crystal quartz wedges with a compensating quartz block in optical contact with the. Babinet Compensator. A quarter wave plate or a half wave plate produces only a fixed path difference between the ordinary and the extraordinary rays and can. The author reports a new kind of birefringent compensator made of a bent single- mode optical fibre. Birefringent properties result from variation of the geometry.

Remember me on this computer. Theoretical fringe profiles with crossed Babinet compensators in testing concave aspheric surfaces A. Photographs show how the simple fringe systems are formed out of the complex babinet compensator. Please login to set citation alerts. When the long birefringent wedge is positioned such that the total thickness of the two stacked wedges is equal babinet compensator the thickness of the compensator comppensator, the net retardance of light passing through the Soleil-Babinet compensator will be zero.
