38-508-INK 12.5mm Dia. x 45.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 38-508-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 to near-infrared (VIS-NIR) spectrum, specifically catering to wavelengths between 400 and 1000nm.
The lens's geometry is characterized by its edge thickness of 1.14mm and center thickness of 2mm. The effective focal length (EFL) is 45mm, and the radius of curvature (R1) is 23.26mm. The back focal length (BFL) is 43.68mm, and both the inner and outer radii are 0mm, indicating a flat surface on the opposite side of the curved face.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is coated with edm visnir0sp2002000 on both the front and back surfaces, a coating specifically designed for VIS-NIR applications.
