47-385-INK 20.0mm Dia. x 80.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 47-385-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 20.0mm and a focal length of 80.0mm, making it suitable for a wide range of applications. The lens is coated with edm visnir0sp2002000 on both the front and back surfaces, enhancing its performance in the visible to near-infrared spectrum (400-1000nm).
The lens's geometry is well-defined, with a thickness at the edge of 1.13mm and a center thickness of 2.35mm. The inner and outer radii are both zero, indicating a circular shape. The lens's effective focal length (EFL) is 80.0mm, and the back focal length (BFL) is 78.45mm. The radius of curvature (R1) is 41.48mm.
This lens is made of n-bk7 schott, a popular material in optical systems due to its excellent optical properties. The wavelength for this lens is 587.6nm. The lens is inked, a process that aids in handling and prevents contamination during assembly.
The item data provided does not include information about the lens's applications or any additional features. However, given its specifications, this lens could be suitable for applications that require a plano-convex lens with a visible to near-infrared coating, such as imaging systems, beam shaping, or light collimation.
