38-468-INK 18.0mm Dia. x 20.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 38-468-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a base shape of a circle, has a diameter of 18.0mm and a thickness at the edge of 1.46mm, transitioning to a thickness at the center of 4.3mm. The effective focal length (EFL) of this lens is 20.0mm, making it suitable for a variety of optical applications.
The lens features an inner radius of 0mm and an outer radius of 0mm, with a front radius (R1) of 15.7mm. The back focal length (BFL) is 17.59mm. The lens is made from n-sf11 Schott, a high-index glass with excellent transmittance in the visible spectrum.
The 38-468-INK 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 reflectance, and protection against environmental factors, making it ideal for use in various applications.
