47-859-INK 5.0mm Dia. x 12.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm

The 47-859-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 5.0mm, is designed for use within the visible to near-infrared spectrum, specifically between 400-1000nm. The lens has a front and back coating of edm visnir0sp2002000, which is a broadband anti-reflection coating optimized for the visible and near-infrared range.

The lens has a thickness of 1.25mm at the edge and 1.77mm at the center, with an effective focal length (EFL) of 12mm. The radius of curvature for the first surface (R1) is 6.22mm, and the back focal length (BFL) is 10.83mm. The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.

This lens is designed for use in various applications that require a compact, high-performance lens within the specified wavelength range. Its plano-convex design allows for efficient light transmission while minimizing spherical aberration. The broadband anti-reflection coating further enhances its performance by reducing surface reflections, thereby increasing the amount of light transmitted through the lens.
