BS020 30:70 (R:T) Non-Polarizing Beamsplitter Cube; 1 inch 700-1100nm

The BS020 is a high-quality non-polarizing beamsplitter cube, designed and manufactured by Thorlabs. This beamsplitter cube is specifically engineered for use in the 700-1100nm wavelength range, making it an ideal choice for a wide array of applications in the optical spectrum.

The BS020 boasts a reflection ratio of 30:70 (R:T), meaning it reflects 30% of the incident light and transmits 70%. This ratio is consistent across the entire specified wavelength range, ensuring predictable and reliable performance. The beamsplitter cube is constructed from n-BK7 Schott glass, a material known for its excellent optical properties and durability.

The BS020 features a cube side of 1 inch (25.4mm), making it compatible with a wide range of optical systems and components. The beamsplitter cube is coated with Thorlabs' proprietary tho cbs bbar700-1100 coating on all surfaces, enhancing its performance and longevity.

This beamsplitter cube is designed in a cube shape, which provides superior stability and alignment capabilities compared to other beamsplitter designs. The BS020 is currently in stock and available for immediate shipping, as indicated by its weblink status.
