49-911 20.0mm Dia. x 25.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 49-911 is a Plano-Convex Spherical Lens, sourced from the reputable optical components vendor, Edmund Optics. This lens boasts a diameter of 20.0mm and a focal length of 25.0mm, making it a compact yet powerful addition to any optical system.
The lens is crafted from the high-quality material, n-sf11 schott, which is known for its excellent optical properties. This material, combined with the Plano-Convex geometry, ensures minimal spherical aberration and distortion, providing clear, sharp images.
The 49-911 features a front and back coating of edm nir-i std curve. This coating enhances the lens's performance in the near-infrared spectrum, specifically between 600nm and 1050nm. It improves light transmission, reduces surface reflections, and increases the lens's durability, making it an ideal choice for applications in this spectral range.
The lens has a central thickness of 4mm and an edge thickness of 1.26mm, providing a robust structure while maintaining a low profile. The inner and outer radii are both 0mm, indicating a uniform curvature across the lens surface.
