88-694-INK 15.0mm Dia. x 18.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-694-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 15.0mm, is designed for use in the visible light spectrum, specifically between 350-700nm, making it suitable for a wide range of optical applications.
The lens features a front and back coating of EDM VIS EXT, which is a broadband anti-reflection coating designed for use in the visible spectrum. This coating helps to reduce surface reflections, thereby increasing the amount of light transmitted through the lens.
The geometry of the lens includes a thickness of 1.4mm at the edge and 4.0mm at the center, with an effective focal length (EFL) of 18.0mm. The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a plano surface on one side and a curved surface on the other. The radius of curvature (R1) of the curved surface is 12.11mm.
The lens is made from N-SF5 Schott, a high-quality optical glass known for its excellent transmittance and low autofluorescence. This makes it an ideal choice for applications that require high light transmission and low background noise.
