The 69-469 is a Plano-Convex spherical lens, boasting a 6.0mm diameter and a focal length of 48.0mm, specifically designed for use with a 785nm wavelength. This lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens is constructed from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material makes the lens suitable for a wide range of applications, including laser systems and imaging applications.
The lens features a front and back coating of EDM Las V-Coat 785, a specialized coating that enhances the lens's performance in laser applications. This coating is designed to increase the transmission of the 785nm wavelength, thereby improving the efficiency and effectiveness of the lens in its intended use.
The geometry of the lens is carefully designed to optimize its performance. The lens has a thickness of 1.42mm at the edge and 1.6mm at the center, providing a robust structure while maintaining a low profile. The effective focal length (EFL) is 48mm, and the radius of curvature (R1) is 24.81mm, contributing to the lens's high-quality imaging capabilities.
