38-441-INK 9.0mm Dia. x 20mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 38-441-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a base shape of a circle, has a diameter of 9.0mm and a thickness at the edge of 1.17mm, while the center thickness measures 2.2mm. The effective focal length (EFL) of this lens is 20mm, making it suitable for various optical applications.
The lens's front and back surfaces are coated with EDM VIS EXT, a coating that extends the visible range of the lens to 350-700nm. This coating enhances the lens's performance in transmitting and refracting light, making it an ideal choice for applications that require high-quality imaging or light transmission.
The lens's inner and outer radii are 0, indicating a sharp transition from the flat (plano) surface to the curved (convex) surface. The radius of curvature (R1) of the curved surface is 10.34mm. The back focal length (BFL) of the lens is 18.55mm.
This lens is made of N-BK7 Schott, a high-quality optical glass known for its excellent optical properties, including high transmission in the visible spectrum and low optical dispersion. This material makes the lens durable and suitable for various applications in the optical industry.
