48-340 9mm Dia. x -9mm FL; MgF2 Coated; Double-Concave Lens 400-700nm
The 48-340 is a high-quality double-concave lens, boasting a 9mm diameter and a focal length of -9mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for immediate purchase, as indicated by its "in stock" status on the vendor's website.
The lens is crafted from n-sf11 Schott, a material known for its exceptional optical properties. It features a spherical geometry, with an inner radius and outer radius of 0, and a thickness that varies from 3.48mm at the edge to 2.25mm at the center. The effective focal length (EFL) of the lens is -9mm, and the back focal length (BFL) is -9.61mm.
The 48-340 is coated with MgF2, a standard coating that provides excellent optical performance across the visible spectrum, specifically designed for the wavelength of 587.6nm. This coating is applied to both the front and back surfaces of the lens, ensuring optimal light transmission and reducing unwanted reflections.
