47-381 6.0mm Dia. x 48.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 47-381 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 6.0mm diameter and a focal length of 48.0mm, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence.
The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating designed for use in the visible and near-infrared spectrum (400-1000nm). This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving image quality and contrast.
The geometry of the lens includes a thickness edge of 1.42mm and a thickness center of 1.6mm. The inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The lens's base shape is circular, adding to its versatility and applicability in various optical systems.
The lens's EFL (Effective Focal Length) is 48mm, a critical specification that determines the lens's magnification power. The R1 (Radius of Curvature) is 24.81mm, and the BFL (Back Focal Length) is 46.95mm. These parameters are essential in designing and integrating the lens into optical systems.
