47-474 9.0mm Dia. x 22.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm

This is a 9.0mm diameter, plano-convex lens with a focal length of 22.0mm, designed for use within the visible light spectrum (425-675nm). The lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.

The lens is made from Schott's n-BK7 glass, a popular choice due to its excellent optical properties and wide transparency range. The plano-convex geometry, where one side is flat and the other is curved, is ideal for a variety of applications, including beam shaping and collimation.

The front and back surfaces of the lens are coated with Edmund Optics' standard VIS-0 coating, designed for 0-degree angle of incidence. This coating enhances the lens's performance by reducing surface reflections and improving transmission within the visible light spectrum.

The lens's geometry includes a 1.0mm edge thickness and a 1.93mm center thickness, providing structural integrity while minimizing unnecessary weight. The inner and outer radii are both 0mm, indicating a sharp curvature on the convex side.

Please note that the lens's effective focal length (EFL) is 22.0mm, and the radius of curvature (R1) is 11.37mm. The back focal length (BFL) is 20.73mm. These specifications are crucial for accurate system design and component placement.
