88-638-INK 6.0mm Dia. x 7.5mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-638-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 6.0mm, is designed for use within the visible light spectrum, specifically between 350-700nm. The lens features a front and back coating of edm vis ext, which is a type of anti-reflective coating that enhances transmission and reduces surface reflections.
The lens has a thickness of 1.68mm at the edge and 2.5mm at the center, with an effective focal length (EFL) of 7.5mm. The radius of curvature for the first surface (R1) is 5.89mm, and the back focal length (BFL) is 6.1mm. The lens does not have an inner or outer radius, indicating a uniform curvature across the lens surface.
The lens is made from n-sf11 schott, a high-index glass material known for its excellent optical properties. This material, combined with the lens's design, provides high dispersion and low chromatic aberration, making it suitable for a wide range of applications.
