47-348-INK 25.0mm Dia. x 75.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm

This product is a Plano-Convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as 47-348-INK, boasts a diameter of 25.0mm and a focal length of 75.0mm, making it suitable for a wide range of optical applications.

The lens is constructed from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The base shape of the lens is circular, and it features a plano-convex geometry, where one side is flat, and the other side is curved. The lens's edge thickness is 2.43mm, while the center thickness is 4.5mm, providing a solid structure for efficient light transmission.

The lens's front and back surfaces are coated with the EDM VIS-0 standard curve coating, designed for visible light within the wavelength range of 425-675nm. This coating enhances the lens's performance by reducing surface reflections and improving transmission, making it an ideal choice for applications that require high light transmission and minimal loss.

The lens's inner and outer radii are 0mm, indicating a sharp curvature that contributes to its focusing power. The lens's effective focal length (EFL) is 75mm, and the back focal length (BFL) is 72mm, providing a clear focus and optimal image formation.
