38-469-INK 18.0mm Dia. x 25.0mm FL; VIS-EXT; Inked; Plano-Convex Lens
The 38-469-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 18.0mm and a focal length of 25.0mm, making it suitable for a variety of optical applications. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high homogeneity.
The lens features a Visible Extended (VIS-EXT) coating on both the front and back surfaces. This coating enhances the lens's performance in the visible spectrum, specifically between 350-700nm, by reducing reflection and increasing transmission. The coating also provides protection against environmental factors, ensuring the longevity of the lens.
The geometry of the lens includes a thickness of 1.65mm at the edge and 5.3mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on one side and a curved surface on the other. The radius of curvature (R1) is 12.92mm, and the back focal length (BFL) is 21.51mm.
