45-170 50mm Dia. x 200mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
This is a 50mm diameter by 200mm focal length double-convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens is made from the high-quality material, n-BK7 Schott, and features a standard MgF2 coating on both the front and back surfaces.
The lens boasts a double-convex geometry, characterized by its base shape of a circle and a shape defined as spherical. The lens's geometry details include a thickness of 2mm at the edge and 5.05mm at the center, with an effective focal length (EFL) of 200mm. The first and second radii of curvature are 205.86mm and -205.86mm, respectively, resulting in a back focal length (BFL) of 198.33mm.
The lens is designed to operate within the wavelength range of 400-700nm, with a central wavelength of 587.6nm. The MgF2 coating on both surfaces is standard, providing excellent anti-reflection properties, further enhancing the lens's performance.
