38-449 12.5mm Dia. x 15mm FL; VIS-EXT Coated; Plano-Convex Lens VIS-EXT 350-700nm
The 38-449 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. It boasts a diameter of 12.5mm and a focal length of 15mm, making it a compact and efficient optical component. The lens is made from n-sf11 Schott, a high-index glass with excellent optical properties, contributing to its high performance.
The lens features a VIS-EXT coating on both the front and back surfaces. This coating, specific to the visual spectrum (350-700nm), enhances the lens's transmission capabilities, reducing unwanted reflections and improving overall light transmission. This makes the 38-449 an ideal choice for applications that require high-transmission optics within the specified wavelength range.
The geometry of the lens is well-defined, with a center thickness of 3.1mm and an edge thickness of 1.3mm. The inner and outer radii are 0mm, indicating a uniform curvature. The lens's effective focal length (EFL) is 15mm, and the back focal length (BFL) is 13.26mm, providing a clear understanding of the lens's optical properties.
