47-236 25 x 25mm 50:50 (R:T) N-BK7 Broadband Non-Polarizing Cube Beamsplitter; t=25mm Telecom 1100-1620nm

The 47-236 is a high-quality non-polarizing cube beamsplitter, designed and manufactured by Edmund Optics. This beamsplitter is specifically engineered for the telecom wavelength range of 1100-1620nm, making it an ideal choice for applications in this spectrum.

The beamsplitter features a 25mm x 25mm geometry, with a cube side length also measuring 25mm. This compact size allows for easy integration into various optical systems. The beamsplitter has a 50:50 reflection to transmission ratio, meaning it reflects 50% of the incident light and transmits the remaining 50%. This ratio is consistent across the entire telecom wavelength range, ensuring predictable and reliable performance.

The 47-236 is constructed from N-BK7 Schott glass, a material known for its excellent optical properties and broadband transmission characteristics. The beamsplitter's coating is another notable feature. Both the front and back surfaces are coated with an ideal broadband AR coating, while the left and right surfaces, as well as the hypotenuse 1, are coated with an EDM 47-013 coating. The hypotenuse 2 surface is coated with an ideal broadband AR coating. This comprehensive coating ensures optimal performance and durability.
