32-880 35mm Dia. x 70mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
The 32-880 is a high-quality double-convex lens, boasting a 35mm diameter and a focal length of 70mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens is crafted from n-BK7 Schott, a popular optical glass due to its excellent transparency and low dispersion. The lens's geometry is characterized by a 3.12mm edge thickness and a 7.5mm center thickness, with an effective focal length (EFL) of 70mm. The front and back surfaces of the lens are coated with MgF2, a type of anti-reflective coating that enhances transmission in the 400-700nm wavelength range.
The lens's base shape is circular, and its surface geometry includes a first radius (R1) of 71.08mm and a second radius (R2) of -71.08mm. The back focal length (BFL) is 67.48mm, and both the inner and outer radii are 0mm. The lens's shape is spherical, which is a common choice for its simplicity and wide range of applications.
