Purging of a light beam path in an effective manner that minimizes the affect of the purging requirement on system throughput. In one embodiment, the invention is incorporated into a birefringence measurement system that has several components for directing light through a sample optical element and thereafter detecting and analyzing the light. The segment of the beam path through the sample is isolated to reduce the volume that requires continual purging.

Purging light beam paths in optical equipment

A holder for optical elements, or samples, in an optical setup. The holder is readily adjustments to accommodate samples of various sizes, such as cylindrical shaped samples of various diameters. The holder provides stable support for the sample, irrespective of the size of the sample and maximizes the area of the sample through which a light beam may pass as part of the analysis of the optical properties of the sample.
