Where to Buy Polarizers

Optometrics, a Dynasil company, manufactures ruled wire grid polarizers on CaF₂ (calcium fluoride) and ZnSe (zinc selenide), together covering a wavelength range from 2.5 to 20 microns and holographic wire grid polarizers on CaF₂ (calcium fluoride), ZnSe (zinc selenide), BaF₂ (barium fluoride), KRS-5 and Ge (germanium), covering a wavelength region from 2.5 to 30 microns.

At Knight Optical, we stock a vast range of polarisers suitable for a variety of high-precision projects; with optics covering the <0.2 to >2 μm wavebands. For applications requiring customised optical solutions, we also provide custom-made polarisers for seamless integration with high-tech devices. Our polariser offering comprises sheet, circular, crystal and cube polarisers as well as Lyot depolarisers and polariser assemblies.

LASEROPTIK offers various types of polarizers, including thin-film (TFP) devices, cube polarizers (CP) and broadband polarizers (BBPOL). We can work in different wavelength ranges from the mid-IR (2.1 μm) to the UV (157 nm).

At Shanghai Optics we produce some of the highest quality dichroic polarizers. Our dichroic plate beamsplitters are manufactured with a special design and proprietary manufacturing approach, allowing us to attain steep edges and flat, high reflection and transmission bands.

The almost complete transmission and reflection provided by our dichroic polarizers means that very little stray light gets through the imaging system. This results in high contrast image and a very good signal to noise ratio, as compared to other polarizers.

Our dichroic polarizers feature a UV grade fused silica, JGS1, or JGS2 substrate, coated with a hard dielectric coating. These glass polarizers have a much higher damage threshold than their plastic counterparts, and are suitable for precision applications. Our coatings fully meet MIL-STD-810F and MIL-C-484971 requirements, and we have a variety of different options available.

Artifex Engineering offers a wide range of polarizers including crystal polarizers (Glan-Taylor, Glan-Thompson, …), dielectric polarizers, dichroic polymer polarizer sheets and wire grid polarizers. In addition, we offer polarization rotators and depolarizers. As with all our products, we offer customization for our polarizers. Visit our product page for more detailed information for each polarizer. We look forward to your inquiry.
