rochon prism การใช้

Rochon prisms are commercially available, but for many applications other polarisers are preferred.
The Rochon prism was invented by and is named after S閚armont prisms the undeviated ray is ordinary on both sides of the interface.
The S閚armont prism is similar in construction and action to the Rochon prism, as in both polarizers the ray that is not deflected is the o-ray after the internal interface, while the deflected ray is the e-ray.
However, in the Rochon prism, it is the p-polarized ray that remains an o-ray on both sides of the interface, and is therefore not deflected, while the s-polarized ray changes from o-ray to e-ray and is therefore deflected.
