The BS069 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 infrared spectrum.
The beamsplitter cube features a 5mm cube side, providing a compact and robust design that is ideal for integration into optical systems. The beamsplitter itself is a 90:10 (R:T) non-polarizing type, meaning it reflects 90% of the incident light and transmits 10% of the incident light, regardless of the polarization state of the light. This makes it a versatile component for applications where maintaining the polarization state of the light is not a critical concern.
The BS069 is coated with Thorlabs' proprietary tho cbsbbar1100-1600 coating on all surfaces, ensuring high damage threshold and excellent spectral performance across the entire 1100-1600nm wavelength range. The cube is shaped as a right-angle prism, with hypotenuse faces coated with tho 9010nbk7cbs11001 and tho cbsbbar1100-1600 coatings. This unique design ensures high efficiency and low loss, making the BS069 an excellent choice for applications where low insertion loss and high efficiency are critical.
