38-319 25.4mm Dia. x 75.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
This product is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as item number 38-319, is characterized by its 25.4mm diameter and a focal length of 75.0mm. The lens is designed for the visible light spectrum, specifically catering to the wavelength of 587.6nm.
The lens is made from the high-quality material, N-BK7 Schott, a borosilicate glass known for its excellent optical properties. This material ensures high transmission and low dispersion, making it ideal for a wide range of optical applications.
The lens features a front and back coating of EDM VIS-0 STD CURVE, a broadband anti-reflection coating optimized for the visible spectrum. This coating significantly reduces surface reflections, enhancing the overall transmission of the lens.
The lens geometry includes a 1.36mm edge thickness and a 3.5mm center thickness. The inner and outer radii are 0mm, indicating a plano surface on one side and a curved surface on the other. The radius of curvature of the curved surface is 38.76mm, and the back focal length is 72.69mm.
