LBTEK-Your Trusted Partner For Optoelectronic Experiments!

Product Description

Operating wavelength: 900 nm-1300 nm
Extinction ratio (Tp:Ts): >1000:1
Application: separating P-polarized light and S-polarized light

The LBTEK 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. LBTEK 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 LBTEK provides the users with high-quality optical products at reasonable prices.

Broadband Polarizing Beamsplitter Cubes, AR Coating: 900 nm-1300 nm, 30 mm Coaxial Cube Mounts

Operating wavelength: 900 nm-1300 nm
Extinction ratio (Tp:Ts): >1000:1
M3 threaded holes on the side, compatible with the 30 mm coaxial systems
Four SM1 internal threads on the side, compatible with SM1 lens tubes for installation

LBTEK integrates the 25.4 mm polarizing beamsplitter 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.

The LBTEK 30 mm Coaxial Beamsplitter Cube can be directly fixed using the post, and the housing surface is engraved with an optical path schematic diagram for easy use by customers.

Broadband Polarizing Beamsplitter Cubes, AR Coating: 900 nm-1300 nm, Unmounted

Five cube sizes available: 5 mm, 10 mm, 12.7 mm, 20 mm, and 25.4 mm
Operating wavelength: 900 nm-1300 nm
Extinction ratio (Tp:Ts): >1000:1
Without coaxial cube housings for mounting

LBTEK offers polarizing beamsplitter cubes in five sizes: 5 mm, 10 mm, 12.7 mm, 20 mm, and 25.4 mm. The 25.4 mm beamsplitter cube is pre-installed in a coaxial cube housing for convenient, ready-to-use integration. Any of the four sides 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 for transmitting P-polarized light and reflecting S-polarized light.

The LBTEK Coaxial Cubes are commonly used for mounting beamsplitter cubes.
