PBS
A polarizing beamsplitter prism separates incident unpolarized light into two orthogonal linearly polarized beams. P-polarized light is fully transmitted, while S-polarized light is reflected at 45 degrees and exits at 90 degrees to the P beam. Two high-precision right-angle prisms are cemented together, with a dielectric polarizing beamsplitter coating on one hypotenuse. Taopu offers PBS prisms in various specifications.

Non-polarizing beamsplitter prism (NPBS) UBPBS032 Polarization Optics Uni-lens
Dimensions: 3.2 mm × 3.2 mm × 3.2 mm Standard Wavelength [Optional standard wavelengths, not a continuous overall range]: 450-680, 650-850, 900-1200, 1250-1570, 1500-1610 nm Material: N-SF2 grade A optical glass
A non-polarizing beamsplitter (NPBS), also called an NPBS cube beamsplitter, is a more complex type made from two right-angle prisms joined at their hypotenuse faces. Before bonding, the cementing face of one prism receives a metal-dielectric coating with the required reflection characteristics, a specified reflection percentage, and color. Coating absorption loss is minimized, and transmission and reflection ratios can be set to 10%, 20%, 30%, 40%, 50%, and other values.

Glan-Taylor prism Polarization Optics 100optics
Material: α-BBO，Calcite or YVO4 Wavelength Range [Material=α-BBO]: 200-3500 nm Extinction Ratio [Material=α-BBO]: ＜5×10⁻⁶
Glan Taylor Polarizer is made of two same birefringence material prisms which are separated by an air space. The polarizer with on side escape window is suitable for low to medium power application. Glan Taylor Polarizer will divide an entering unpolarized beam into beam rays, one is the extraordinary that is transmitted through the other side, and another is the ordinary ray that is totally internally reflected absorbed.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
