38-518-INK 12.7mm Dia. x 100.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 38-518-INK is a plano-convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.7mm, is designed for use within the visible to near-infrared spectrum (VIS-NIR), specifically catering to wavelengths between 400 and 1000nm.
The lens's geometry is characterized by a thickness of 1.31mm at the edge, increasing to 1.7mm at the center. The effective focal length (EFL) is 100mm, and the radius of curvature (R1) is 51.68mm. The back focal length (BFL) measures 98.88mm, while the inner and outer radii are 0mm each, indicating a plano surface on the opposite side of the convex surface.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens's surfaces are coated with the EDM VISNIR0SP2002000 coating on both the front and back, enhancing its performance within the VIS-NIR spectrum.
