47-913 25mm Dia. x -100 FL; VIS 0deg Coated; Plano-Concave Lens 425-675nm
The 47-913 is a Plano-Concave Spherical Lens, sourced from Edmund Optics, with a 25mm diameter and a -100mm focal length (FL). This lens is designed for use within the visible light spectrum, specifically between 425-675nm, making it suitable for a wide range of optical applications.
The lens is fabricated from N-BK7 Schott glass, a popular choice due to its excellent optical properties and versatility. The lens features a plano-concave geometry, meaning one side is flat while the other is curved inward. This particular lens has an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature across the lens.
The 47-913 lens boasts a center thickness of 3.5mm and an edge thickness of 4.85mm, providing a robust structure while maintaining a sleek profile. The back focal length (BFL) is -102.31mm, slightly longer than the focal length due to the lens's concave shape.
The lens is coated with the EDM VIS-0 STD curve on both the front and back surfaces. This coating enhances the lens's performance within the visible light spectrum, reducing surface reflections and improving transmission.
