49-519 6.0mm Dia. x -15 FL; NIR I Coated; Plano-Concave Lens 600-1050nm
The 49-519 is a 60mm diameter Plano-Concave lens with a focal length of -15, 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 wavelength range.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It has a diameter of 6mm and a thickness of 2.49mm at the edge, reducing to 2mm at the center. The lens's base shape is circular, and it features a Spherical geometry.
The 49-519 is coated with Edmund Optics' NIR-I standard curve on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared spectrum, improving transmission and reducing reflection.
The lens's inner and outer radii are both 0, indicating a simple Plano-Concave design. The back focal length is -16.32mm, and the effective focal length is -15mm.
This lens is currently in stock and available for immediate purchase from the Edmund Optics website.
