BS080 30:70 (R:T) Non-Polarizing Beamsplitter Cube; 20 mm 700-1100nm

The BS080 is a non-polarizing beamsplitter cube, designed and manufactured by Thorlabs, offering a 30:70 (R:T) reflection-to-transmission ratio. This beamsplitter cube is specifically designed for use within the 700-1100nm wavelength range, making it suitable for a wide array of applications within the near-infrared spectrum.

The cube features a 20mm side length, providing a compact and robust solution for beam splitting applications. The beamsplitter cube is constructed using n-BK7 Schott glass, a material well-known for its excellent optical properties and versatility.

The BS080's coating is another notable feature. Both the front, back, left, right, hypotenuse 1, and hypotenuse 2 surfaces are coated with Thorlabs' proprietary tho cbs bbar700-1100 coating. This coating ensures optimal performance and durability within the intended wavelength range.
