48-759-INK 20.0mm Dia. x 40.0mm FL; NIR I; Inked; Plano-Convex Lens NIR I 600-1050nm
The 48-759-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 20.0mm and a focal length of 40.0mm, making it suitable for a variety of optical applications. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex). The radius of curvature for the curved side is 20.67mm. The lens has a central thickness of 4.9mm and an edge thickness of 2.32mm. The back focal length (BFL) is 36.77mm, and the effective focal length (EFL) is 40.0mm.
The lens is coated with Edmund Optics' NIR-I standard curve coating on both the front and back surfaces. This coating is designed for use in the near-infrared region, specifically between 600nm and 1050nm, enhancing its transmission capabilities in this spectrum. The coating also provides protection against environmental factors, ensuring the lens maintains its performance over time.
