63-582 20mm Dia. x 20mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
This is a 20mm diameter, double-convex lens with a focal length of 20mm, sourced from the renowned optical components vendor, Edmund Optics. The lens is made from n-SF11 Schott material, a high-index glass known for its excellent optical properties.
The lens features a standard MgF2 coating on both the front and back surfaces, which is designed to reduce reflection and increase transmission in the 400-700nm wavelength range. This coating enhances the lens's performance in various applications, including imaging, illumination, and beam manipulation.
The lens's geometry includes a thickness of 1.6mm at the edge and 5mm at the center, with a back focal length of 18.55mm. The first and second radii of curvature are 30.25mm and -30.25mm, respectively. The lens's design is spherical, ensuring high-quality imaging and minimal aberrations.
