The 47-859 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 5.0mm and a focal length of 12.0mm, making it suitable for a variety of applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a VIS-NIR coating, specifically edm visnir0sp2002000, on both the front and back surfaces. This coating is designed to enhance the lens's performance in the visible and near-infrared spectrum, specifically between 400 and 1000nm. The coating reduces reflection and increases transmission, improving the lens's overall efficiency.
The lens's geometry includes a thickness of 1.25mm at the edge and 1.77mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a flat surface on the non-curved side of the lens. The lens's effective focal length (EFL) is 12mm, and the back focal length (BFL) is 10.83mm.
This lens is currently in stock and available for purchase through the Edmund Optics website. Its detailed specifications and high-quality materials make it a reliable choice for various optical applications.
