38-471 18.0mm Dia. x 50.0mm FL; VIS-EXT Coated; Plano-Convex Lens VIS-EXT 350-700nm
The 38-471 is a Plano-Convex Spherical Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens boasts an 18.0mm diameter and a 50.0mm focal length (FL), making it suitable for a wide range of optical applications.
The lens is crafted from the high-quality material, n-BK7 Schott, a borosilicate glass known for its excellent optical properties and durability. The base shape of the lens is circular, and it features a plano-convex geometry, with the convex side facing outwards.
The lens has a thickness of 1.28mm at the edge and 2.9mm at the center. The effective focal length (EFL) is 50.0mm, and the radius of curvature (R1) is 25.84mm. The back focal length (BFL) is 48.09mm, and both the inner and outer radii are 0mm.
The 38-471 lens is coated with EDM VIS EXT on both the front and back surfaces. This coating enhances the lens's performance in the visible light spectrum, specifically within the wavelength range of 350-700nm. The coating ensures high transmission, low reflection, and increased durability, making this lens an excellent choice for various optical systems.
