Depolarizer Type
Back to Top
|
| ||
| Your choices are... | |||
| Wedge Depolarizers | The optic axis of the crystalline quartz wedge lies in the plane of the wedge, and at 45° to the input polarization. This has the effect of acting like a retardation plate which has a variable retardation across the aperture. | ||
| Lyot Depolarizers | Lyot depolarizers consist of two crystalline quartz plates assembled with their optic axes lying in the plane of the plates, aligned at 45°. One plate is exactly twice the thickness of the other. Depolarization occurs due to the production of varying amounts of circularly and elliptically polarized radiation of different wavelengths. | ||
| Other | Any other depolarizer type not mentioned. | ||

| |||
| Diameter: | The diameter of the depolarizer when viewed straight on. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Clear Aperture | This is the clear aperture of retardation plates. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Thickness | This is the thickness of retardation plates. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Operating Temperature: | The temperature range in which the device is designed to operate. | ||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
