BS031 50:50 (R:T) Non-Polarizing Beamsplitter Cube; 2 inch 400-700nm

The BS031 is a 50:50 non-polarizing beamsplitter cube, designed and manufactured by Thorlabs. This beamsplitter cube is a crucial component in various optical systems, facilitating the division of an incident light beam into two separate beams of equal intensity. The BS031 is specifically designed for use within the 400-700nm wavelength range, making it suitable for a wide array of applications.

This beamsplitter cube boasts a cube side of 50.8mm, ensuring stability and durability in its construction. The BS031 features a reflection coefficient of 0.5 and a transmission coefficient of 0.5, promoting a balanced division of the incident light beam. The cube is crafted from n-BK7 Schott glass, a material renowned for its excellent optical properties and versatility.

The BS031 is coated with Thorlabs' proprietary tho cbs bbar400-700 coating on all of its surfaces, enhancing its performance within the specified wavelength range. This coating ensures high damage threshold, low scatter, and minimal optical loss, thereby contributing to the overall efficiency of the optical system.
