32-905 25mm Dia. x 400mm FL; MgF2 Coated; DCX N-K5 Lens for 400-700nm
The 32-905 is a high-quality spherical lens, boasting a 25mm diameter and a focal length of 400mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is specifically designed for use within the 400-700nm wavelength range.
The lens is crafted from the high-performance glass material, N-K5, supplied by Schott. This material is known for its excellent optical properties, making it an ideal choice for a wide range of applications. The lens features a standard MgF2 coating on both the front and back surfaces, which enhances its overall light transmission capabilities and reduces surface reflections.
The geometry of the lens is meticulously designed, with an edge thickness of 4.63mm and a center thickness of 5mm. The effective focal length (EFL) is 400mm, and the back focal length (BFL) is 398.75mm. The first and second radii of the lens are 417.54mm and -417.54mm respectively, contributing to its superior optical performance.
This lens is a Convex-Convex (CC) type, with a circular base shape. It is important to note that the inner and outer radii are both zero, indicating that this lens does not have any threading or other features on its edges.
