47-386 20.0mm Dia. x 150.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 47-386 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 20.0mm and a focal length of 150.0mm, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence.
The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating designed for use in the visible and near-infrared spectrum (400-1000nm). This coating enhances the lens's performance by reducing surface reflections, thereby increasing the amount of light transmitted through the lens.
The geometry of the lens includes a thickness of 2.35mm at the edge and 3.0mm 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 radius of curvature (R1) is 77.52mm, and the back focal length (BFL) is 148.02mm.
According to the vendor, this item is currently in stock, and the web link provided leads to its product page on the Edmund Optics website. This lens is a versatile optical component, ideal for applications that require a lens with a long focal length and high transmittance in the visible and near-infrared spectrum.
