This BK7-BSP-12.7-400-700-60:40 is a 12.7 mm diameter, 3mm thick beamsplitter, specifically designed for broadband applications within the 400-700nm wavelength range. The beamsplitter is sourced from Simtrum, a reputable vendor in the optical industry.
The beamsplitter is made of N-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. This material ensures high transmission and low absorption across the visible spectrum. The beamsplitter features a sim bs604040070045 coating on the front surface, which is designed to provide a 60:40 (R:T) split ratio at the central wavelength of 588nm. This means that approximately 60% of the incident light will be reflected, while 40% will be transmitted.
The beamsplitter's thin lens shape allows for easy integration into various optical systems. It is important to note that the beamsplitter's performance is valid and it is currently in stock, according to the vendor's website.
