38-470-INK 18.0mm Dia. x 30.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 38-470-INK is a plano-convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a base shape of a circle and a diameter of 18.0mm. The lens's thickness at the edge is 1.52mm, while its center thickness measures 4.4mm. The effective focal length (EFL) of this lens is 30.0mm.
The lens's front and back surfaces are coated with edm vis ext, a type of coating that extends the visible range of the lens. The lens's inner and outer radii are both zero, indicating a plano surface on one side and a curved surface on the other.
The lens is made of n-bk7 schott, a popular optical glass with high homogeneity and low auto-fluorescence. It is designed to work at a wavelength of 587.6nm. The lens's geometry, including its diameter, thickness, and EFL, make it suitable for a wide range of optical applications.
