88-630-INK 5.0mm Dia. x 7.5mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-630-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 5.0mm, is designed for use in the visible light spectrum, specifically between 350-700nm, as indicated by its VIS-EXT coating.
The lens's geometry is defined by its edge thickness of 1.34mm and center thickness of 1.9mm, with an effective focal length (EFL) of 7.5mm. The front surface of the lens has a radius of curvature (R1) of 5.89mm, and a back focal length (BFL) of 6.43mm. The lens's inner and outer radii are both zero, indicating a uniform curvature.
The lens is made from n-SF11 Schott, a high-index glass with excellent optical properties. The lens's coating, VIS-EXT, is applied to both the front and back surfaces, enhancing its performance in the visible light spectrum.
This lens is inked, a process that adds a dye or pigment to the lens to make it more visible and easier to handle during assembly. The inking process does not affect the lens's optical properties.
