62-599-INK 25.4mm Dia. x 25.4mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 62-599-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 25.4mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically catering to wavelengths between 400nm and 1000nm.
The lens's geometry is defined by its diameter, thickness at the edge (2.43mm), and thickness at the center (7mm). The effective focal length (EFL) is 25.4mm, and the radius of curvature (R1) is 19.93mm. The back focal length (BFL) is 21.48mm, and both the inner and outer radii are 0mm, indicating a flat surface on the lens's incident side.
The lens is made from n-SF11 Schott, a popular material for optical elements due to its high refractive index and low dispersion. This makes it ideal for applications requiring high image quality and color correction.
The lens features a VIS-NIR coating, specifically the EDM VISNIR0SP2002000 coating, on both the front and back surfaces. This coating is designed to enhance the lens's performance in the VIS-NIR spectrum, reducing reflection and increasing transmission.
