49-483 15mm Dia. x 30mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm

The 49-483 is a high-quality double-convex lens, 15mm in diameter and 30mm in focal length, designed for use in the near-infrared (NIR) spectrum, specifically between 600 and 1050nm. This lens is sourced from the reputable optical vendor, Edmund Optics, ensuring top-tier performance and reliability.

The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The double-convex shape, with radii of curvature of 30.5mm and -30.5mm, provides a balanced optical performance. The lens has an effective focal length (EFL) of 30mm, making it suitable for a wide range of optical applications.

The 49-483 features a standard coating of EDM NIR-I on both the front and back surfaces. This coating enhances the lens's performance in the NIR spectrum, improving transmission and reducing unwanted reflections. The coating is designed to the standard curve, ensuring consistent performance across different lenses.

The lens has a center thickness of 4mm and an edge thickness of 2.13mm, providing robustness and durability. The lens is circular in shape, allowing for easy integration into various optical systems. The back focal length (BFL) is 28.82mm, which should be considered when designing the optical layout.
