Description
Experience the precision and quality of Photonchina's Wollaston Polarizers, designed to meet the diverse needs of optical applications. These polarizers are expertly crafted to separate an incident beam into two distinct rays: the extraordinary and ordinary rays, with a deviation angle that varies depending on the wavelength. This unique capability ensures that both rays are efficiently transmitted through the other surface, providing unparalleled performance in optical systems.
Photonchina's Wollaston Polarizers are available in a variety of materials, including a-BBO, Calcite, YVO4, and Quartz, each offering a specific wavelength range to suit different requirements. The materials are selected for their high-quality optical properties, ensuring minimal beam deviation and optimal parallelism. The surface quality of these polarizers is meticulously maintained at a 20/10 standard, and they boast a wavefront distortion of λ/4 at 632.8 nm, ensuring precision in every application.
Each polarizer is designed to withstand high-intensity applications with a damage threshold of over 500 MW/cm², making them robust and reliable for demanding environments. With a single MgF2 coating and a sleek black anodized aluminum mount, these polarizers not only perform exceptionally but also feature a durable and aesthetically pleasing design. Trust Photonchina to deliver polarizers that provide exceptional performance and reliability for all your optical needs.
