BS048 30:70 (R:T) Non-Polarizing Beamsplitter Cube; 5 mm 1100-1600nm

The BS048 is a non-polarizing beamsplitter cube, designed and manufactured by Thorlabs, a leading vendor in the field of optical components. This beamsplitter cube is specifically designed for use in the 1100-1600nm wavelength range, making it suitable for a wide range of applications in the near-infrared spectrum.

The beamsplitter cube features a 5 mm cube side, providing a compact and robust design that is ideal for integration into optical systems. The beamsplitter itself has a reflection coefficient of 0.3 and a transmission coefficient of 0.7, making it a 30:70 (R:T) beamsplitter. This ratio is fixed and non-polarizing, meaning it will split incoming light equally regardless of its polarization state.

The BS048 is coated with Thorlabs' proprietary tho cbsbbar1100-1600 coating on all surfaces, ensuring high damage threshold and excellent spectral performance. This coating is specifically designed for use in the 1100-1600nm wavelength range, providing high reflectivity and transmission across this spectrum.

The beamsplitter cube is made from n-bk7 Schott glass, a high-quality optical material known for its excellent optical properties and high damage threshold. This glass is used for both the hypotenuse faces of the cube, while the other faces are coated with the tho cbsbbar1100-1600 coating.
