32-987 6mm Dia. x -6mm FL; MgF2 Coated; Double-Concave Lens 400-700nm
The 32-987 is a double-concave lens with a 6mm diameter and a focal length of -6mm, sourced from Edmund Optics. This lens is designed for use within a wavelength range of 400-700nm, making it suitable for a wide range of optical applications.
The lens is constructed from n-sf11 Schott, a high-index glass with excellent optical properties. It features a spherical shape, with radii of curvature of -9.74mm and 9.74mm for the first and second surfaces, respectively. The lens has an edge thickness of 2.29mm and a center thickness of 1.5mm, providing robustness and durability.
The 32-987 lens is coated with MgF2, a standard coating that offers high transmission and low reflection across the visible spectrum. This coating is applied to both the front and back surfaces of the lens, enhancing its performance and longevity.
Please note that the lens has an inner radius of 0mm and an outer radius of 0mm, indicating a simple, double-concave design. The effective focal length (EFL) is -6.41mm, slightly longer than the nominal focal length due to the thickness of the lens.
This lens is currently in stock, according to the vendor's website, and is ready for immediate use in your optical system.
