49-908 15.0mm Dia. x 18.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 49-908 is a Plano-Convex Spherical Lens, sourced from the reputable optical vendor, Edmund Optics. This lens boasts a 15.0mm diameter and a focal length of 18.0mm, making it suitable for a wide range of optical applications.
The lens is crafted from n-SF5 Schott, a high-quality optical material known for its excellent transmittance and durability. The base shape of the lens is circular, contributing to its versatility in various optical systems.
The 49-908 features a front and back coating of EDM NIR-I STD Curve, a specialized coating designed to optimize performance in the near-infrared spectrum (600-1050nm). This coating enhances the lens's light transmission capabilities and reduces surface reflections, thereby improving overall system efficiency.
The lens's geometry includes a thickness of 1.4mm at the edge and 4.0mm at the center, providing a balanced profile for efficient light transmission. The inner and outer radii are 0mm, indicating a uniform curvature throughout the lens.
The lens's EFL (Effective Focal Length) is 18.0mm, a critical parameter in determining the lens's focusing capabilities. The BFL (Back Focal Length) is 15.61mm, which is the distance from the lens's rear surface to the focal point.
