11-288 15 x 15mm 50:50 (R:T) N-BK7 Broadband Non-Polarizing Cube Beamsplitter; t=15mm VIS-EXT 400-640nm
The 11-288 is a 15 x 15mm 50:50 (R:T) N-BK7 Broadband Non-Polarizing Cube Beamsplitter, designed for use in the visible spectrum. This beamsplitter, sourced from Edmund Optics, features a cube side length of 15mm, making it suitable for a wide range of optical applications.
The beamsplitter is designed to reflect 50% of incident light while transmitting the remaining 50%. This 50:50 (R:T) ratio ensures balanced light distribution, making it ideal for applications requiring even light splitting. The beamsplitter is made from N-BK7 glass, a popular choice for its high homogeneity, low auto-fluorescence, and excellent transmission in the visible spectrum.
The 11-288 features ideal broadband anti-reflection coatings on all surfaces, including the hypotenuse faces. This coating reduces surface reflections, enhancing the overall transmission of the beamsplitter. The hypotenuse faces are coated with EDM 11-287, a specialized coating designed for optimal performance in the visible spectrum.
This beamsplitter is designed for use in the visible spectrum, specifically between 400 and 640nm. This broadband range makes it versatile for various applications, from basic laser systems to complex imaging setups. The beamsplitter's cube shape ensures stability and alignment, making it a reliable choice for precision optical systems.
