BK7-NPBSC-20-900-1200 20 x 20 x 20 mm N-BK7 Broadband Non-Polarizing Cube Beamsplitter 900-1200nm

The BK7-NPBSC-20-900-1200 is a non-polarizing cube beamsplitter, designed and manufactured by Simtrum. This beamsplitter is a crucial component in various optical systems, facilitating the division of incident light into reflected and transmitted components.

The beamsplitter is constructed with N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. The glass is cut and polished into a cube shape, with each side measuring 20 mm, providing a compact and robust design.

The beamsplitter's coating is another notable feature. Both the front and back surfaces are coated with an ideal broadband anti-reflective (AR) coating, reducing unwanted reflections and improving transmission. The left and right surfaces also feature the same ideal broadband AR coating for added protection and performance.

The hypotenuse faces of the beamsplitter are treated differently. The first hypotenuse is coated with a Sim BB-NPBS 1200 45 coating, specifically designed for broadband non-polarizing beamsplitters. The second hypotenuse is coated with the ideal broadband AR coating, ensuring optimal performance across the entire spectral range.

The beamsplitter's spectral range is from 900nm to 1200nm, making it suitable for a wide range of applications. The reflection and transmission coefficients are both 0.5, indicating a balanced division of incident light.
