LBTEK-Your Trusted Partner For Optoelectronic Experiments!

Product Description

Operating wavelength: 420 nm-680 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: 420 nm-680 nm, 30 mm Coaxial Cube Mount

Operating wavelength: 420 nm-680 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

The 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 side for compatibility with the 30 mm coaxial systems. Additionally, the housing is equipped with four SM1 internal threaded ports on the side, 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: 420 nm-680 nm, Unmounted

Operating wavelength: 420 nm-680 nm
Extinction ratio (Tp:Ts): >1000:1
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.
