87-919-INK 5.0mm Dia. x 25.0mm FL; NIR I; Inked; Plano-Convex Lens NIR I 600-1050nm
The 87-919-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 in the near-infrared spectrum, specifically between 600-1050nm, as indicated by its NIR I coating. The lens has a front and back coating of edm nir-i std curve, which enhances its performance in the specified wavelength range.
The lens has a thickness of 1.36mm at the edge and 1.6mm at the center, with an effective focal length (EFL) of 25mm. The radius of curvature for the first surface (R1) is 12.92mm, and the back focal length (BFL) is 23.95mm. The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The lens is inked, which is a process where a dye is applied to the edge of the lens to indicate its orientation. This is particularly useful during assembly to ensure the correct orientation of the lens. The lens is circular in base shape, making it suitable for a wide range of applications.
