49-528 12.0mm Dia. x -24 FL; NIR I Coated; Plano-Concave Lens 600-1050nm
The 49-528 is a Plano-Concave Lens with a diameter of 12.0mm, a focal length of -24, and a central thickness of 3.5mm. The lens is sourced from Edmund Optics, a leading supplier of optical components. It is designed for use in the near-infrared spectrum, specifically between 600-1050nm, making it suitable for a wide range of applications in this region.
The lens is made from n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. This includes a high Abbe number, low auto-fluorescence, and excellent transmission in the visible and near-infrared regions. The lens features a spherical shape, with a radius of curvature of -12.4mm on the front surface and a back focal length of -26.32mm.
The 49-528 is coated with Edmund Optics' NIR I coating, which is standard for this type of lens. This coating is designed to enhance the lens' performance in the near-infrared region, improving its transmission and reducing reflections. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance.
