FTIR Beam Splitter
A beamsplitter/compensator set is used in a Michelson-interferometer FTIR spectrometer. Such spectrometers generally have one movable mirror. The two mirrors lie in perpendicular interferometer arms. The beamsplitter sits at the vertex of the right angle, oriented at 45° to each mirror. It splits incident light into two parts, ideally 50%/50%, which travel along the two arms and are reflected back by the mirrors.

Cemented PBS Prism PBS2005
Beam Splitters
U-photonics
Material: K9 or ZF Glass; Fused Silica Wavelength Range: 350~2300nm Dimensional Tolerance: +/-0.1mm
A polarizing beamsplitter cube separates unpolarized input into orthogonal linear polarizations: P transmits fully and S reflects at 45°, exiting at 90° to P. Two precision UV-fused-silica right-angle prisms are bonded, with a dielectric polarizing coating on one hypotenuse. Any surrounding face can be an entrance, but best polarization performance uses the perpendicular face of the coated prism; a black dot on top identifies it. Laser-line cubes offer Tp:Ts>3000:1. Four transmitting faces have single-wavelength V-type AR coatings with reflection <0.25% at the design wavelength. Ten options are 405, 532, 633, 780, 808, 830, 850, 1030, 1064 and 1550nm.

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.
