The 63-719-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning from 400 to 1000nm.
The lens features a 10mm diameter and an effective focal length (EFL) of 25mm, making it suitable for a wide range of optical applications. The achromatic design, which combines two different types of glass (N-BK7 and N-SF5), effectively minimizes chromatic aberration, ensuring sharp and clear imaging.
The lens geometry includes a central thickness of 3.5mm, with a slight increase to 3.76mm at the edge. The inner and outer radii are zero, indicating a simple, circular shape. The first and second radii of curvature (r1 and r2) are 15.37mm and -11.1mm respectively, while the third radius (r3) is -31.47mm.
Both the front and back surfaces of the lens are coated with the EDM VIS-NIR 0SP2002000 coating, which is designed to enhance transmission in the specified wavelength range. This coating also provides protection against environmental factors, ensuring the longevity and durability of the lens.
