63-579 18mm Dia. x 18mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
The 63-579 is a high-quality double-convex lens, boasting an 18mm diameter and a focal length of 18mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock. The lens is made from n-SF11 Schott, a material known for its excellent optical properties.
The lens features a magnesium fluoride (MgF2) coating on both the front and back surfaces. This coating is standard and provides a wide spectral range of 400-700nm, making it suitable for a variety of applications. The MgF2 coating is known for its ability to reduce reflection and increase transmission, enhancing the overall performance of the lens.
The geometry of the lens is meticulously designed, with an edge thickness of 1.44mm and a center thickness of 4.5mm. The effective focal length (EFL) is 18mm, and the back focal length (BFL) is 16.69mm. The radii of the curvature are R1 = 27.22mm and R2 = -27.22mm. The lens is circular in shape, adding to its versatility and functionality.
