BS009 50:50 (R:T) Non-Polarizing Beamsplitter Cube; 5 mm 1100-1600nm

The BS009 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 is a 50:50 (R:T) non-polarizing type, meaning it reflects and transmits incoming light equally, regardless of its polarization state. This makes it a versatile component for applications that do not require polarization control.

The BS009 is coated with Thorlabs' proprietary tho cbsbbar1100-1600 coating on all surfaces, ensuring high reflectivity and transmissivity within the specified wavelength range. This coating is designed to maintain its performance characteristics even under high-power operation, making the BS009 suitable for use in demanding optical systems.

In terms of geometry, the BS009 is a cube-shaped beamsplitter, with hypotenuse faces coated with tho 50nbk7cbs1100160 and tho cbsbbar1100-1600 coatings. This geometry, combined with the high-quality coatings, ensures efficient and reliable beam splitting performance.
