89-153 12mm Dia. x 30mm FL; VIS-EXT Coated; Double-Convex Lens VIS-EXT 350-700nm
The 89-153 is a double-convex lens offered by Edmund Optics, boasting a 12mm diameter and a focal length of 30mm. This lens is designed for use within the visible light spectrum, specifically between 350-700nm, making it suitable for a wide range of optical applications.
The lens is constructed from Schott's n-BK7 glass, a popular material in optical systems due to its excellent optical properties and high Abbe number. The base shape of the lens is circular, and it features a front and back coating of EDM VIS-EXT, a broadband anti-reflection coating that enhances transmission within the specified wavelength range.
The geometry of the lens includes a 2.5mm edge thickness and a 3.7mm center thickness. The effective focal length (EFL) is 30mm, while the back focal length (BFL) is 28.75mm. The first and second radii of curvature are 30.36mm and -30.36mm, respectively. The lens is currently in stock and available for immediate purchase.
