49-524 9.0mm Dia. x -27 FL; NIR I Coated; Plano-Concave Lens 600-1050nm
The 49-524 is a 9.0mm diameter Plano-Concave Lens with a focal length of -27, sourced from Edmund Optics. This lens is designed for use within the near-infrared spectrum, specifically between 600-1050nm, making it suitable for a wide range of applications in this region.
The lens is constructed from n-sf11 Schott, a high-index glass with excellent transmittance in the NIR region. It features a plano-concave geometry, meaning one side is flat while the other is curved inward. This design is often used to diverge or spread out light, making it ideal for use in collimating or beam expanding applications.
The 49-524 lens has a thickness of 3.42mm at the edge and 3mm at the center. The inner and outer radii are both 0, indicating a simple, direct curvature. The back focal length is -28.68mm, slightly longer than the focal length due to the lens's concave shape.
Both the front and back surfaces of the lens are coated with Edmund Optics' NIR I standard curve coating. This coating is designed to enhance the lens's performance in the NIR region, improving its transmission and reducing reflections. The coating status is currently in stock, ensuring quick and reliable delivery.
