49-530 12.0mm Dia. x -48 FL; NIR I Coated; Plano-Concave Lens 600-1050nm
The 49-530 is a Plano-Concave Lens with a diameter of 12.0mm, a focal length of -48, and a central thickness of 3.5mm. The lens is sourced from Edmund Optics and is currently in stock. It is designed for use within the near-infrared spectrum, specifically between 600-1050nm, making it suitable for a variety of applications within this range.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens features a spherical shape, with a front radius of -24.81mm and a back focal length of -50.31mm. The edge thickness of the lens is 4.12mm.
The 49-530 is coated with Edmund Optics' NIR-I standard curve coating on both the front and back surfaces. This coating is designed to enhance the lens' performance within the near-infrared spectrum, improving transmission and reducing reflection.
