38-315 18.0mm Dia. x 30.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as 38-315, has a diameter of 18.0mm and a focal length of 30.0mm, making it a compact yet powerful optical tool.
The lens is made from the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including low dispersion and high transmission in the visible spectrum. This makes the lens suitable for a wide range of applications, particularly those requiring high image quality and precision.
The lens features a standard coating, specifically the EDM VIS-0 std curve, on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections and increasing transmission in the visible spectrum, which ranges from 425 to 675nm.
The geometry of the lens includes a thickness of 1.52mm at the edge and 4.4mm at the center. The radius of curvature (R1) is 15.51mm, and the back focal length (BFL) is 27.1mm. The lens's shape is spherical, and it has no inner or outer radius, indicating a uniform curvature throughout.
