14-643 25 x 25 mm 50:50 (R:T) N-BK7 Standard Cube Beamsplitter; t=25mm 700-1100nm

The 14-643 is a 25 x 25 mm Cube Beamsplitter from Edmund Optics, designed for use in the near-infrared spectrum. This beamsplitter is a 50:50 type, meaning it evenly splits incoming light between its reflection and transmission paths.

The beamsplitter is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. The cube itself has a side length of 25 mm, making it suitable for a wide range of optical applications. The beamsplitter's thickness is also 25 mm, adding to its robustness and stability.

The beamsplitter's coating is another notable feature. Both the front and back surfaces are coated with an ideal broadband anti-reflective coating, reducing unwanted reflections and increasing transmission. The left and right surfaces also have the same coating, further enhancing the beamsplitter's performance.

The hypotenuse faces of the beamsplitter are also coated. The first hypotenuse is coated with EDM NIR R50 T50, a coating specifically designed for near-infrared applications. The second hypotenuse is coated with the ideal broadband anti-reflective coating, ensuring optimal performance.

This beamsplitter is designed to operate in the 700-1100 nm range, making it ideal for a wide range of near-infrared applications. Its high-quality construction, robust design, and excellent optical properties make it a reliable choice for any optical system that requires a beamsplitter in this wavelength range.
