47-388 25.0mm Dia. x 750.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm

The 47-388 is a Plano-Convex lens with a diameter of 25.0mm and a focal length of 750.0mm, sourced from the reputable optical components vendor, Edmund Optics. This lens is designed for use within the visible to near-infrared spectrum, specifically catering to wavelengths between 400-1000nm, making it suitable for a wide range of optical applications.

The lens is constructed from N-BK7 Schott glass, a popular choice due to its excellent optical properties and versatility. The Plano-Convex geometry, where one side is flat and the other is curved, aids in focusing light, making this lens ideal for use in imaging systems, beam shaping, or other applications requiring light concentration.

The 47-388 features a front and back coating of edm visnir0sp2002000, a broadband anti-reflection coating specifically designed for the visible to near-infrared range. This coating reduces surface reflections, enhancing transmission and improving overall system performance.

The lens has a center thickness of 3.2mm and an edge thickness of 3mm, providing robustness and durability. The inner and outer radii are 0mm, indicating a simple, straightforward design. The effective focal length (EFL) is 747.89mm, and the back focal length (BFL) is 750mm, which are crucial specifications for designing and integrating this lens into optical systems.
