The 68-411 is a 50 x 50 mm rectangular beamsplitter, designed with a 60:40 (R:T) ratio, meaning it reflects 60% and transmits 40% of the incident light. This beamsplitter is made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties and high damage threshold. The glass has a thickness of 3mm, providing robustness and stability.
This beamsplitter is designed for the visible spectrum, specifically for wavelengths between 400 and 700nm, making it suitable for a wide range of applications in this spectrum. The beamsplitter features a thin lens shape, which helps to minimize unwanted reflections and scattering, thereby improving the overall efficiency and quality of the optical system.
The front surface of the beamsplitter is coated with EDM 68-399, a coating specifically designed to enhance the performance of the beamsplitter. This coating ensures high reflectivity and transmission rates, consistent with the 60:40 ratio, across the entire visible spectrum.
The beamsplitter is sourced from Edmund Optics, a leading manufacturer of optical components, ensuring high quality and reliability. According to the vendor's website, the beamsplitter is currently in stock, indicating its availability for immediate purchase and use.
