Product Description

l Operating wavelength: 1200 nm-1600 nm

l Extinction ratio (Tp:Ts): >1000:1

l Application: separating P-polarized light and S-polarized light

     The Tuniu Broadband Polarizing Beamsplitter Cube consists of two right-angle prisms. The prism with a black dot on top indicates that its hypotenuse is coated with a dielectric polarizing beamsplitter coating, which reflects S-polarized light and transmits P-polarized light. Any of the four sides of the cube can serve as the incident surface to separate P-polarized and S-polarized light. For optimal polarization performance, it is recommended that the incident light enters from the right-angle side of the prism coated with the polarizing beamsplitter coating. Tuniu offers polarizing beamsplitter cubes made of N-SF1 material in various sizes, with four anti-reflection coating options of 420 nm-680 nm, 620 nm-1000 nm, 900 nm-1300 nm, and 1200 nm-1600 nm. All our optical components are finely processed and undergo strict quality control to ensure that Tuniu provides the users with high-quality optical products at reasonable prices.

Attributes

Broadband Polarizing Beamsplitter Cubes, AR Coating: 1200 nm-1600 nm, 16 mm Coaxial Cube Mounts

l M3 threaded holes on the side, compatible with the 16 mm coaxial systems

l Four SM05 internal threads on the side, compatible with SM05 lens tubes for installation

     Tuniu integrates the 20.0 mm polarizing beam splitter cube in a cube housing compatible with the 16 mm coaxial systems. A reference line is engraved on the top of the housing to indicate optical path direction. The housing features M3 threaded holes on the sides, and ensures compatibility with the 16 mm coaxial systems via the Ø4 mm coaxial system mounting posts. Additionally, the housing includes four SM05 internal threaded ports on the side, allowing simultaneous compatibility with the 12.7 mm lens tubes. Moreover, the coaxial cube is equipped with M4 threaded holes at the bottom for mounting posts.

Broadband Polarizing Beamsplitter Cubes, AR Coating: 1200 nm-1600 nm, 30 mm Coaxial Cube Mounts

l M3 threaded holes on the side, compatible with the 30 mm coaxial systems

l Four SM1 internal threads on the side, compatible with SM1 lens tubes for installation

     Tuniu integrates the 25.4 mm polarizing beam splitter cube in a cube housing compatible with the 30 mm coaxial systems. A reference line is engraved on the top of the housing to indicate optical path direction. The housing features M3 threaded holes on the sides for compatibility with the 30 mm coaxial systems. Additionally, the housing provides four SM1 internal threaded ports on the sides, allowing simultaneous compatibility with 25.4 mm lens tubes. Moreover, the coaxial cube is equipped with M4 threaded holes at the bottom for mounting posts.

Broadband Polarizing Beamsplitter Cubes, AR Coating: 1200 nm-1600 nm, Unmounted

l Five cube sizes available: 5 mm, 10 mm, 12.7 mm, 20 mm, and 25.4 mm

l Without coaxial cube housings for mounting

     All four sides of the Tuniu Unmounted Polarizing Beamsplitter Cube are coated with anti-reflection coatings (Ravg<0.5%). One of the right-angle prisms has a hypotenuse coated with a beamsplitter coating, and a black dot is marked with a pencil on the frosted top surface of this prism. For optimal optical performance, it is recommended to have the light incident from the right-angle face of the prism with the beamsplitter coating. Tuniu offers cube adapter mounts in various sizes. When clamping the cube, the overall dimension is 25.4 mm. When used with the Cube Mount CM-3, it is compatible with the 30 mm coaxial systems.
