BS081 30:70 (R:T) Non-Polarizing Beamsplitter Cube; 20 mm 1100-1600nm
The BS081 is a non-polarizing beamsplitter cube, designed and manufactured by Thorlabs, a leading global supplier of photonics equipment. This beamsplitter cube is specifically engineered for use in the 1100-1600nm wavelength range, making it an ideal choice for a wide array of applications within this spectrum.
The BS081 boasts a reflection ratio of 30:70 (R:T), meaning that it reflects 30% of the incident light and transmits 70%. This ratio is consistent across all surfaces of the cube, ensuring uniform performance regardless of the incident angle. The cube itself is constructed from n-bk7 Schott glass, a material renowned for its excellent optical properties and durability.
The BS081 features a cube side of 20mm, providing a compact yet robust design. The beamsplitter cube is coated with tho cbsbbar1100-1600 on all surfaces, except for the hypotenuse faces which are coated with tho 3070nbk7cbs11001 and tho cbsbbar1100-1600. This specific coating configuration ensures optimal performance within the intended wavelength range.
