Wedge Prism
The wedge prism is an optical prism with inclined beveled surfaces, primarily used in the field of optics for beam control and deflection. With a small inclination angle on both sides, it causes the optical path to deflect towards the side that is thicker. Using a single wedge prism can shift the incident optical path by a certain angle; combining two wedge prisms can function as a deformation prism, mainly used for correcting laser beams. In the field of optics, the wedge prism is an advanced optical path adjustment device. Two rotatable prisms can adjust the direction of the outgoing beam within a certain range (10°). Wedge prisms play a crucial role in laser beam control. They can operate alone, deflecting laser beams to specific angles; a single prism can shift the incident beam by one diopter (equivalent to a 1 cm shift over a 1-meter distance). Alternatively, they can be paired for beam deflection. Two wedge prisms can function as deformation prisms, correcting the elliptical beam output from a laser tube and deflecting the beam at different angles within a range of 4θ. By individually rotating the two prisms, beam shaping can be achieved, commonly used for beam scanning at different positions in imaging applications.

PBS beamsplitter prism Prisms 100optics
Material [Shared by the standard/high-precision columns; Original cell colspan2]: N-BK7.Fused Silica,N-SF11,or depend on request Clear Aperture [Standard specification]: ≥85 % Dimension Tolerance [Standard specification]: ±0.1 mm
A polarizing beamsplitter 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. Made from a pair of cemented high-precision right-angle prisms, with a polarizing beamsplitter dielectric coating on the hypotenuse of one prism.

Triangular Prism Prisms 100optics
Material: K9 or ZF glass, etc. Dimensional Tolerance [Two original parallel options without grade distinctions]: ±0.2，±0.1 Surface Quality: 60 / 40
Prisms turn and displace light at specified angles and can adjust image orientation. Their shape and function depend on their interaction with light. Incident light may reflect from one or more surfaces before exiting, or refract while passing through the substrate. Baijing offers forms including triangular prisms, pentaprisms, Dove prisms, Powell prisms, roof prisms, and corner cubes.

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.
