Glan Taylor Polarizer is a polarization optic composing two wedge prisms with their slanted sides assembled with air-gap construction. To a great extent, Glan Taylor polarizers are similar to Glan laser polarizers. Glan Taylor polarizers also leverage the manipulation of angles and refraction indices to realize the screening of polarization components. The orientations of the optical axes of the first prism and the second prism are equivalent, when an incident light hits 90 degrees on one of the end faces of the polarizer, the polarizer separates the light beam into two orthogonal polarization: the s polarization (i.e. the ordinary component), the p polarization (i.e. the extraordinary polarization). The angles of the constituent prisms are contrived upon deliberation. Their optical axes are parallel to the plane of the entrance, so that when the o component and the e component enter the polarizer, the o component experiences total internal reflection (TIR) at the interface between two prisms, while the e component keeps propagating, since the incident angle at the interface is close to Brewster’s angle, a large proportion of extraordinary light is transmitted.

Hangzhou Shalom EO offers Stocked and Custom Glan Taylor Polarizers. Each polarizer consists of two prisms joined utilizing an air-spaced design, with the black anodized aluminum housing available in circular or rectangular forms. It is worth noting that The major difference between a Glan Taylor polarizer and a Glan laser polarizer is that a Glan Taylor polarizer does not have an escape port dug on its housing, and therefore is appropriate for low and medium power lasers, but not suggested for high-power applications.

Three substrate materials are available: Calcite, Alpha-BBO, and YVO4. The maximum extinction ratio is a staggering 200000:1. Miscellaneous coating options including protective coating (P-coating), and broadband AR coating with transmission spectral range spanning from ultraviolet, visible, to infrared are procurable. Standardized aperture sizes are accessible in stock, including:φ6mm, φ10mm, φ12.7mm, φ15mm, and φ20mm. Other sizes are available upon request. Besides, Shalom EO also offers a full portfolio of Glan polarizers, including Glan Laser Polarizers, which are capable of handling higher power, and Glan Thompson Polarizers which feature large acceptance angles, if you are interested, you might click on the bold text to learn more.
