89-126 5mm Dia. x 15mm FL; VIS-EXT Coated; Double-Convex Lens VIS-EXT 350-700nm
This is a high-quality double-convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. The lens, identified as item number 89-126, boasts a 5mm diameter and a 15mm focal length, making it suitable for a wide range of optical applications.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It features a double-convex geometry, with radii of curvature of 15.16mm for the first surface and -15.16mm for the second, contributing to its high optical performance.
The lens is coated with EDM VIS-EXT, a broadband anti-reflection coating designed for use in the visible spectrum, specifically between 350nm and 700nm. This coating significantly reduces surface reflections, enhancing the lens's transmission and overall optical efficiency.
The lens has an edge thickness of 1.58mm and a center thickness of 2mm, providing robustness and durability. The back focal length is 14.33mm, and the effective focal length is 15mm, which is the distance from the lens's principal plane to the focal point.
