63-571 10mm Dia. x 30mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm

This is a high-quality double-convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. The lens, identified as the 63-571 model, boasts a 10mm diameter and a focal length of 30mm, making it suitable for a wide range of optical applications.

The lens is made from Schott's n-BK7 glass, a popular material in the optical industry due to its excellent optical properties and high chemical resistance. The lens's geometry features a double-convex shape, with a center thickness of 2.5mm and an edge thickness of 1.68mm, providing a solid structure for precise optical operations.

The lens's front and back surfaces are coated with Magnesium Fluoride (MgF2), a common coating material known for its ability to reduce surface reflections and increase transmission in the spectral range of 400-700nm. This coating enhances the lens's performance in various applications, including imaging, beam shaping, and light collimation.

The item data also provides the effective focal length (EFL) of the lens, which is 30mm, and the back focal length (BFL) of 29.17mm. The radii of curvature for the first and second surfaces are 30.58mm and -30.58mm, respectively.
