Broadband Polarizing Beamsplitter

Shanghai Optics, a leading optics components manufacturer in China, offers high performance broadband polarizing cube beamsplitters. These polarizing cube beamsplitters combine the robust design of traditional laser polarizing beamsplitters with the versatility of broadband polarizing cubes, suitable for a wide spectral range. Featuring a durable structure, the polarization components are securely housed within the cube, making them ideal for use in various applications, including high-power laser systems.

The dielectric coating on the hypotenuse face efficiently separates  s- and p-polarized light, achieving high extinction ratios for the transmitted beam (TP > 1000:1). Additionally, the AR coating minimizes reflection losses, enhancing performance across the specified spectral range. We offer three wavebands: 450-680 nm for visible spectrum lasers, 650-850 nm for diode lasers, and 1300-1600 nm for telecommunications applications. These high power beamsplitters meet power laser performance standards while offering superior durability and polarizing precision.
