49-520 6.0mm Dia. x -18 FL; NIR I Coated; Plano-Concave Lens 600-1050nm
The 49-520 is a Plano-Concave Lens with a 6.0mm diameter, manufactured by 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 within this wavelength range.
The lens features a significant focal length of -18, which is typical for Plano-Concave lenses and contributes to its light-converging properties. The lens has a central thickness of 2.0mm and an edge thickness of 2.4mm, providing a robust structure while maintaining a compact form.
The lens is made from N-BK7 Schott glass, a common material in optical systems due to its excellent optical properties and high Abbe number. This ensures minimal chromatic aberration and maintains image quality.
The 49-520 is coated with Edmund Optics' NIR-I standard curve coating on both the front and back surfaces. This coating enhances the lens's performance within the near-infrared spectrum, improving transmission and reducing reflection. The coating status is currently in stock, ensuring availability for immediate use.
