63-718-INK 10 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=20mm VIS-NIR 400-1000nm

The 63-718-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 10 mm and a focal length of 20 mm, is designed for use in the visible to near-infrared spectrum, spanning 400-1000 nm.

The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties. The use of these materials in a doublet configuration helps to correct chromatic aberration, ensuring sharp, clear images across the entire spectral range.

The lens features a front and back coating of EDm VIS-NIR 0SP2002000, a broadband anti-reflection coating designed for use in the visible to near-infrared spectrum. This coating reduces surface reflections, improving light transmission and enhancing the overall performance of the lens.

The lens geometry includes a central thickness of 4 mm, with a slight asymmetry introduced by a 1 mm thick region near the edge. The inner and outer radii are not specified, indicating that these are not critical design parameters.

This lens is available for purchase directly from the Edmund Optics website, where it is listed as being in stock at the time of writing. With its high-quality materials, advanced coating, and precise geometry, the 63-718-INK is an excellent choice for a wide range of optical applications.
