48-742 12.0mm Dia. x 72.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, with a diameter of 12.0mm and a focal length of 72.0mm, is designed for use within the near-infrared (NIR) spectrum, specifically between 600-1050nm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The Plano-Convex geometry, where one side is flat and the other is curved, is a common choice for many optical systems due to its ease of use and broad applicability.
The lens features a front and back coating of EDM NIR-I STD Curve. This coating is designed to enhance the lens' performance within the NIR spectrum, improving transmission and reducing unwanted reflections. The edge thickness of the lens is 1.91mm, while the center thickness is 2.4mm, providing a balanced profile for most applications.
The lens's inner and outer radii are both zero, indicating a simple, straightforward design. The back focal length (BFL) is 70.42mm, slightly less than the focal length due to the curvature of the lens. The effective focal length (EFL) is the same as the focal length at 72mm.
