30° - 60° - 90° Littrow Dispersion Prism

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.

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.

Penta Prism is a five-sided prism containing two reflecting surfaces at 45° to each other, and two refracting faces perpendicular to the entering and emerging beams. The standard Penta Prism reflecting surfaces are coated with aluminum or enhanced aluminum.

Material: K9 or fused silica, etc. Dimensional Tolerance: +0.0，-0.2 Surface Quality: 60 / 40

Light pipes use total internal reflection to convert a nonuniform source into a uniform source regardless of its spectral characteristics. Designed for applications requiring uniform light distribution. Baijing offers square and hexagonal structures.

Roof prisms rotate and invert images and bend light by 90°. Suitable for telescopes and other optical instruments that need to invert the objective image, turn it right-side up, and bend the path by 90° to maintain the correct viewing orientation.
