Wollaston Prism - English Definition & Meaning

Definition

A Wollaston prism is another type of polarizing prism used in optics. Similar to a Rochon prism, it splits a beam of light into two beams with orthogonal polarization. However, in a Wollaston prism, both beams are deviated from the original path. It's constructed from two right-angled prisms cemented together. Made from birefringent materials like calcite, the Wollaston prism is known for its high extinction ratio and is used extensively in microscopy, spectroscopy, and other polarization-sensitive applications. 🔬 The divergence of the beams is dependent on the wavelength of the light.

Etymology

The Wollaston prism is named after William Hyde Wollaston, an English chemist and physicist. Wollaston invented the prism in the early 19th century. He made significant contributions to optics and other scientific fields. The term "prism," as mentioned before, comes from the Greek word "prisma." Wollaston's invention provided a new way to manipulate polarized light. It exemplifies how scientific curiosity can lead to practical innovations. 💡
