70:30 (R:T) Non-Polarizing Beamsplitter Cubes, Unmounted BS1273-A

70:30 (R:T) Non-Polarizing Beamsplitter Cubes, Unmounted — Model BS1273-A

Operating wavelength 400 nm-700 nm, substrate N-BK7.

Product Description

• Substrate material: N-BK7
• Splitting ratio (R:T): 70:30
• 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.

70:30 (R:T) Non-Polarizing Beamsplitter Cubes, Unmounted

• Splitting Ratio: 70:30 (R:T)
• Insensitive to beamsplitting polarization
• Various sizes available

LBTEK offers non-polarizing beamsplitter cubes in five sizes: 5 mm, 10 mm, 12.7 mm, 20 mm, and 25.4 mm.  Any of the four sides of the cube can serve as the incident surface, splitting the transmitted and reflected light according to the specified splitting 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.
