47-356-INK 25.0mm Dia. x 500.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm

The 47-356-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 25.0mm and a thickness at the edge of 2.9mm, which gradually increases to a center thickness of 3.2mm. The effective focal length (EFL) of this lens is 500.0mm, making it suitable for applications requiring long focal lengths.

The lens's front and back surfaces are coated with the EDM VIS-0 standard curve coating, designed to enhance its performance within the visible light spectrum, specifically between 425-675nm. This coating aids in minimizing surface reflections and improving transmission, thereby optimizing the lens's performance in various applications.

The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature across the lens surface. The back focal length (BFL) of this lens is 497.89mm.

The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent optical properties, including high transmittance and low dispersion. This material makes the lens suitable for various applications, especially those requiring high-precision optics.
