38-589-INK 12.5mm Dia. x 50.0mm FL; YAG-BBAR; Inked; Plano-Convex Lens YAG-BBAR 500-1100nm
The 38-589-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.5mm, is designed for use in the visible light spectrum, specifically at a wavelength of 587.6nm. The lens features a front and back coating of YAG-BBAR, which is optimized for use within the 500-1100nm range.
The lens's geometry includes a thickness of 1.23mm at the edge and 2mm at the center. The effective focal length (EFL) is 50mm, and the back focal length (BFL) is 48.68mm. The lens's inner and outer radii are both 0, indicating a planar surface on the uncoated side.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. This lens is inked, which is a process that adds a dye to the lens to make it easier to handle and identify.
