摘要： The sample holder includes support having a thickness and an aperture through the thickness of the support. A tilt mechanism is connected to the support for controlled tilting of the support, and the aperture through the support is configured to have a diameter that increases in a direction through the thickness of the support. This arrangement enables a light beam to pass through the same given area of the sample, irrespective of whether the sample is held perpendicular to the beam or held at a tilted position relative to the beam. In one embodiment, the holder includes an efficient magnetic clamp mechanism for securing the sample to the holder. The holder compactly integrates with tilting mechanisms a sample rotation mechanism.

摘要： 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.

摘要： The disclosure is directed to systems and methods for precisely measuring birefringence properties of large-format samples of optical elements. A gantry-like configuration is employed for precise movement of birefringence measurement system components relative to the sample. There is also provided an effective large-format sample holder that adequately supports the sample to prevent induced birefringence therein while still presenting a large area of the sample to the unhindered passage of light.
