62-475-INK 12.5 mm Dia. N-BAF10/N-SF10 Negative Achromatic Doublet; EFL=-20mm MgF2 400-700nm

The 62-475-INK is a high-quality negative achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 12.5 mm, is designed for use in the 400-700nm spectral range, making it suitable for a wide range of optical applications.

The lens features a focal length of -20mm, which is a common choice for applications requiring a compact, high-performance optical system. The lens is constructed from two types of glass, N-BAF10 and N-SF10, both from Schott, ensuring excellent optical performance.

The lens surfaces are coated with EDM MgF2, a standard coating that provides excellent anti-reflection properties across the specified spectral range. This coating helps to minimize losses due to reflection, thereby improving the overall efficiency of the optical system.

The lens geometry includes a thickness of 7.01mm at the edge, with a central thickness of 2mm and an asymmetric design characterized by radii of curvature of -13.8mm, 9.99mm, and 109.48mm. This design allows for precise control of the optical path, making the lens suitable for use in a wide range of applications.
