This is the BK7-BSC-15-900-1200, a 15 x 15 x 15 mm cube beamsplitter, specifically designed for use in the 900-1200nm wavelength range. The beamsplitter is manufactured by Simtrum, a renowned vendor in the optical industry, and is available for purchase on their website.
The beamsplitter is made of N-BK7, a high-quality glass material produced by Schott, which is known for its excellent optical properties. This beamsplitter features a 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 physical dimensions of the beamsplitter are 15mm x 15mm x 15mm, making it a compact and versatile option for various optical setups. The beamsplitter's coating is ideal broadband AR on all surfaces, ensuring high transmission and low reflection across the entire spectral range.
The BK7-BSC-15-900-1200 is a cube beamsplitter, a type of beamsplitter that is particularly useful in applications where a high degree of stability and alignment is required. The cube design ensures that the beamsplitter remains in a fixed position, reducing the need for frequent realignment.
