63-583 20mm Dia. x 25mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
This is a 20mm diameter, double-convex lens with a focal length of 25mm, sourced from the renowned optical components vendor, Edmund Optics. The lens is made from n-SF11 Schott, a high-index glass with excellent transmittance across the visible spectrum, making it ideal for applications that require high resolution and contrast.
The lens features a standard MgF2 coating on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, particularly in the 400-700nm range. The coating also provides excellent environmental stability, making the lens suitable for use in a wide range of temperatures and humidity levels.
The geometry of the lens includes a thickness of 1.35mm at the edge and 4mm at the center. The front and back radii of curvature are 38.34mm and -38.34mm respectively, resulting in a back focal length of 23.86mm. The lens is spherical in shape, ensuring excellent image quality over a wide field of view.
