High-Precision Optical Rhomboid Prism
A rhomboid prism has an octahedral structure formed by parallel rhombic surfaces and laterally displaces a beam without changing its propagation direction. Typical uses include binocular eyepieces in microscopes and rangefinders, redirecting light without image inversion. High-precision rhomboid prisms are typically made of BK7A or fused silica; coatings can provide beam splitting or polarization separation. They shift laser beams or imaging-system optical axes without changing direction or inverting the image. Applications include optical-path adjustment for clear, stable imaging; angle and distance surveying; periscopes, gun sights and other defense observation equipment; and precise laser-beam path control.

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.
