LBTEK-Your Trusted Partner For Optoelectronic Experiments!

Product Description

Operating wavelength: 620 nm-1000 nm
Extinction ratio (Tp:Ts): >1000:1
Application: separating P-polarized light and S-polarized light

LBTEK offers polarizing beamsplitter cubes with side lengths of 5.0 mm, 10.0 mm, 12.7 mm, 20.0 mm, 25.4 mm, and 50.8 mm, catering to various application scenarios. The 20.0 mm polarizing beamsplitter cube is installed in a cube housing compatible with the 16 mm coaxial systems, featuring M3 threaded holes on the sides for compatibility with the 16 mm coaxial systems. The 25.4 mm polarizing beamsplitter cube is installed in a cube housing compatible with the 30 mm coaxial systems, also featuring M3 threaded holes on the sides for compatibility with the 30 mm coaxial systems. Both coaxial cube housings have engraved lines on the top to indicate the optical path direction and M4 threaded holes on the bottom for mounting posts.

Broadband Polarizing Beamsplitter Cubes, AR Coating: 620 nm-1000 nm, 30 mm Coaxial Cube Mounts

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
Operating wavelength: 620 nm-1000 nm

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 the optical path direction. The housing features M3 threaded holes on the sides for compatibility with 30 mm coaxial systems. Additionally, the housing includes 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: 620 nm-1000 nm, Unmounted

Extinction ratio (Tp:Ts): >1000:1
Operating wavelength: 620 nm-1000 nm
Without coaxial cube housings for mounting

All four sides of the LBTEK 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. LBTEK 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.

The LBTEK Coaxial Cube CM-3 is commonly used for mounting beamsplitter cubes.
