Product Description

Substrate material: N-BK7
Splitting ratio (R:T): 90:10
Operating wavelength: 400 nm-700 nm, 700 nm-1100 nm, 1100 nm-1600 nm
Insensitive to beamsplitting polarization

The LBTEK Non-Polarizing Beamsplitter Cube consists of two right-angle prisms. The prism marked by a black dot on top indicates that its hypotenuse surface is coated with a dielectric non-polarizing beamsplitter coating. Any of the four sides of the cube can serve as the incident surface, splitting the transmitted and reflected light according to the specified ratio. For optimal beamsplitting performance, it is recommended that the incident light enters from the right-angle side of the prism coated with the non-polarizing beamsplitter coating. LBTEK offers non-polarizing beamsplitter cubes made of N-BK7 material in various sizes, with three anti-reflection coating options of 400 nm-700 nm, 700 nm-1100 nm, and 1100 nm-1600 nm. 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.

90:10 (R:T) Non-Polarizing Beamsplitter Cubes, 30 mm Coaxial Cube Mounts

Splitting ratio: 90:10 (R:T)
Insensitive to beamsplitting polarization
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 non-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, and ensures compatibility with the 30 mm coaxial systems via the Ø6 mm coaxial system mounting posts. 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.
