88-655-INK 9.0mm Dia. x 22.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-655-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 9.0mm, 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 broadband anti-reflection coating designed for high transmission in the visible spectrum.
The lens has a thickness of 1.0mm at the edge and 1.93mm at the center, with a focal length (EFL) of 22.0mm. The front surface of the lens has a radius of curvature (R1) of 11.37mm, and the back focal length (BFL) is 20.73mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The lens is inked, which is a process where a dye is applied to the edge of the lens to indicate its orientation. This is particularly useful in applications where the lens may be rotated during assembly, ensuring that the correct surface is facing the source or detector.
