38-325-INK 35.0mm Dia. x 50.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm
This product is a Plano-Convex lens, sourced from the renowned optical vendor, Edmund Optics. The lens, identified as 38-325-INK, is a spherical lens with a base shape of a circle, designed for use within the visible light spectrum, specifically at a wavelength of 587.6nm.
The lens has a diameter of 35.0mm and a thickness at the edge of 1.67mm, while the center thickness is 8.5mm. The effective focal length (EFL) of the lens is 50.0mm, and the radius of curvature (R1) is 25.84mm. The back focal length (BFL) is 44.4mm, and both the inner and outer radii are 0mm.
The lens is made from the material N-BK7 Schott, a popular choice for its high refractive index and low dispersion. The lens features a VIS 0° coating on both the front and back, which is Edmund Optics' standard curve coating for the visible light spectrum. This coating enhances the lens's performance by reducing surface reflections and increasing transmission.
The lens is inked, a process that typically involves applying a dye to the edge of the lens to indicate its orientation. This is particularly useful in assembly and can help prevent incorrect installation.
