Thorlabs' Rochon Prisms split an arbitrarily polarized input beam into two orthogonally polarized output beams. The ordinary ray remains on the same optical axis as the input beam, while the extraordinary ray deviates by an angle, which depends on the wavelength of the light and the material of the prism (see the Beam Deviation graphs in the table to the right). The output beams have a high polarization extinction ratio of >10 000:1 for the MgF2 prism and >100 000:1 for the YVO4 prism. See the table to the right for complete specifications.
Each prism is mounted in a Ø1" anodized aluminum housing. The housing is engraved with the item # and a diagram showing the direction and polarization states of the input and output beams. The prism housing can be mounted in an SM1 lens tube using a retaining ring. The lens tube can then be threaded onto a rotation mount or other SM1-threaded mount for use in a variety of applications.
If your application would benefit from an unmounted Rochon prism or a prism with an AR coating, please contact Tech Support .

Thorlabs' portfolio contains many different kinds of beamsplitters, which can split beams by intensity or by polarization. We offer plate and cube beamsplitters, though other form factors exist, including pellicle and birefringent crystal. Many of our beamsplitters come in premounted or unmounted variants. Below is a complete listing of our beamsplitter offerings.

Polarizer Selection Guide
Thorlabs offers a diverse range of polarizers, including wire grid, film, calcite, alpha-BBO, rutile, and beamsplitting polarizers. Collectively, our line of wire grid polarizers offers coverage from the visible range to the beginning of the Far-IR range. Our nanoparticle linear film polarizers provide extinction ratios as high as 100 000:1. Alternatively, our other film polarizers offer an affordable solution for polarizing light from the visible to the Near-IR. Next, our beamsplitting polarizers allow for use of the reflected beam, as well as the more completely polarized transmitted beam. Finally, our alpha-BBO (UV), calcite (visible to Near-IR), rutile (Near-IR to Mid-IR), and yttrium orthovanadate (YVO4 ) (Near-IR to Mid-IR) polarizers each offer an exceptional extinction ratio of 100 000:1 within their respective wavelength ranges.
