47-121 10 x 10mm 50:50 (R:T) N-BK7 Broadband Non-Polarizing Cube Beamsplitter; t=10mm VIS 430-670nm

The 47-121 is a high-quality non-polarizing cube beamsplitter from Edmund Optics, designed for use in the visible spectrum. This beamsplitter is characterized by its 50:50 reflection-to-transmission ratio, making it an ideal choice for applications that require equal distribution of light between the reflected and transmitted paths.

The beamsplitter is constructed from N-BK7 glass, a popular material in optical systems due to its excellent optical properties and high damage threshold. The glass is shaped into a cube, with each face measuring 10mm, providing a robust and compact design. The cube's thickness is also 10mm, ensuring rigidity and stability.

The 47-121 features broadband anti-reflection coatings on all surfaces, including the hypotenuse faces. These coatings are designed to minimize reflection and maximize transmission across the visible spectrum, from 430nm to 670nm. This broadband coating ensures high-performance and low-loss operation, making it suitable for a wide range of applications.

The beamsplitter's coating on the hypotenuse faces is specifically identified as EDM 47-007, a proprietary coating from Edmund Optics known for its excellent optical performance. The other surfaces are coated with an ideal broadband anti-reflection coating, further enhancing the beamsplitter's performance.
