The 88-699-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, as indicated by its VIS-EXT coating. The lens has a front thickness of 1.26mm and a center thickness of 2.5mm, making it suitable for various optical applications.
The lens's geometry is characterized by an outer radius of 0mm, an inner radius of 0mm, and a base shape that is circular. The effective focal length (EFL) of the lens is 45.0mm, and the back focal length (BFL) is 43.35mm. The radius of curvature (R1) is 23.26mm.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens's coating, VIS-EXT, is applied to both the front and back surfaces, further enhancing its performance in the visible light spectrum.
