47-012 25 x 25mm 50:50 (R:T) N-BK7 Broadband Non-Polarizing Cube Beamsplitter; t=25mm NIR 720-1080nm

The 47-012 is a 25 x 25mm non-polarizing cube beamsplitter, designed for use in the near-infrared (NIR) spectrum of 720-1080nm. This beamsplitter, sourced from Edmund Optics, offers a 50:50 reflection to transmission ratio, making it an ideal choice for applications requiring equal distribution of light.

The beamsplitter is constructed from N-BK7 Schott glass, a material known for its excellent optical properties and broadband transmission capabilities. The cube dimensions are 25mm x 25mm, with a thickness of 25mm, ensuring robustness and stability in its operation.

The coating of the beamsplitter is a crucial aspect of its functionality. The front, back, left, and right surfaces are coated with an ideal broadband anti-reflective (AR) coating, minimizing losses due to reflection and enhancing the overall transmission efficiency. The hypotenuse surfaces are coated with EDM 47-010 and ideal broadband AR coatings, further optimizing the beamsplitter's performance.

This beamsplitter is a cube-shaped volume element, designed to easily integrate into various optical systems. Its broadband capabilities make it versatile, while its non-polarizing nature ensures that the state of polarization is preserved.
