Polarization Components (Polarizers)
Polarizers divide a beam of light into two highly polarized beams, making them ideal for isolation or routing of a specific polarization. Extinction ratio and power handling are important factors to consider when choosing a polarizer, particularly for laser applications. With plate and cube formats to choose from, as well as options for 45° AOI or Brewster angle operation.The most obvious use of a polarizer is purification of a beam's polarization state and/or splitting of a beam into its s- and p-polarized components. Alternatively, it can be used to combine two beams, even at different wavelengths (if a broadband polarizer is used). When the input beams are orthogonally polarized, beam combination can be very efficient. If the input beams are unpolarized, one polarization component from each is combined, achieving effective mixing with ~50% efficiency. A polarizer can also be used in combination with a waveplate to create a passive optical isolator. Rotating the waveplate allows this assembly to work as a variable attenuator (also called a continuously variable beamsplitter)

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.

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.
