BS070 90:10 (R:T) Non-Polarizing Beamsplitter Cube; 10 mm 400-700nm

The BS070 is a non-polarizing beamsplitter cube, designed and manufactured by Thorlabs. This beamsplitter cube is part of the extensive catalog of optical elements offered by 3DOptix, a leading provider of advanced optical simulation software. The BS070 is specifically designed for use in the 400-700nm wavelength range, making it a versatile choice for a wide range of optical applications.

The beamsplitter cube features a cube side of 10mm, providing a compact and robust design. The BS070 boasts a reflection of 0.9 and a transmission of 0.1, making it a 90:10 (R:T) beamsplitter. This ratio is consistent across all faces of the cube, ensuring uniform performance regardless of the incident angle.

The BS070 is coated with a broadband anti-reflection coating (tho cbs bbar400-700) on all faces, including the hypotenuse faces. This coating is designed to reduce surface reflections and increase transmission, thereby enhancing the overall performance of the beamsplitter cube. The coating is specifically designed for use in the 400-700nm wavelength range, ensuring optimal performance within this spectrum.

The BS070 is made from n-BK7 Schott glass, a material known for its excellent optical properties and high damage threshold. This material ensures the BS070 delivers reliable and consistent performance, even under high power conditions.
