The BK7-BSC-20-900-1200 is a standard cube beamsplitter, designed and manufactured by Simtrum. This beamsplitter is a crucial component in various optical systems, particularly those operating within the 900-1200nm wavelength range.
The beamsplitter is constructed with N-BK7 Schott glass, a material known for its excellent optical properties. The geometry of the beamsplitter is a perfect cube, each side measuring 20mm, making it a compact and robust option for various applications.
The beamsplitter features a 50:50 reflection-to-transmission ratio, meaning it evenly splits incoming light into reflected and transmitted components. The coating on the hypotenuse surface is a specific broadband anti-reflection coating (Sim BSC50900120045), designed to minimize reflection and maximize transmission within the specified wavelength range.
The beamsplitter's other surfaces are coated with an ideal broadband anti-reflection coating, further reducing unwanted reflections and ensuring optimal performance. This beamsplitter is available for purchase directly from Simtrum's website, and as of the time of data collection, it is in stock.
