48-707 4.5mm Dia. x 4.5mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 48-707 is a Plano-Convex Spherical Lens, sourced from the renowned optical components manufacturer, Edmund Optics. This lens boasts a 4.5mm diameter and a 4.5mm focal length, making it suitable for a wide range of applications. The lens is fabricated from n-lasf44 Schott, a high-quality optical glass known for its excellent transmittance and durability.
The lens features a front and back coating of EDM NIR-I STD Curve, a specialized coating designed to enhance performance in the near-infrared spectrum, specifically between 600-1050nm. This coating aids in reducing surface reflections and increasing transmission, thereby improving the overall efficiency and quality of the optical system.
The lens geometry includes an edge thickness of 1.8mm and a center thickness of 2.59mm, contributing to its robustness and optical performance. The lens's effective focal length (EFL) is 4.5mm, and its radius of curvature (R1) is 3.61mm. The back focal length (BFL) is 3.05mm, and both the inner and outer radii are 0mm, indicating a planar surface on the opposite side of the convex surface.
