BS062 70:30 (R:T) Non-Polarizing Beamsplitter Cube; 0.5 inch 700-1100nm

The BS062 is a non-polarizing beamsplitter cube designed for use in the 700-1100nm wavelength range, making it suitable for a wide range of optical applications. Manufactured by Thorlabs, this beamsplitter cube boasts a robust construction and high-quality coatings for reliable performance.

The beamsplitter cube features a 0.5 inch (12.7mm) cube side, providing a compact yet substantial platform for beam splitting. The cube is designed with a 70:30 (R:T) split ratio, meaning that 70% of the incident light is reflected while 30% is transmitted. This ratio is consistent across the entire 700-1100nm wavelength range, ensuring predictable and consistent performance.

The BS062 is constructed from n-BK7 Schott glass, a common and reliable material in optical applications due to its excellent optical properties and durability. The beamsplitter coatings on all surfaces are Thorlabs' proprietary CBS BBAR700-1100 coating, designed to minimize reflection and maximize transmission within the specified wavelength range.

In terms of shape, the BS062 is a cube beamsplitter, which is known for its robustness and ease of use in various optical setups. The beamsplitter cube is a volume-based optical element, meaning it has depth as well as width and height, allowing for more complex optical interactions.
