88-661-INK 9.0mm Dia. x 90.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-661-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 a wavelength range of 587.6nm, specifically in the visible light spectrum (VIS) as indicated by its VIS-EXT coating on both the front and back surfaces.
The lens's geometry is characterized by its edge thickness of 1.78mm and center thickness of 2.0mm, with an effective focal length (EFL) of 90.0mm. The front surface of the lens has a radius of curvature (R1) of 46.51mm, and the back focal length (BFL) is 88.68mm. 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 designed for use in the visible light spectrum, enhancing its transmission capabilities within this range (350-700nm). The lens's shape, Plano-Convex, is ideal for applications where a collimated beam is required, or where a focused spot is needed.
