49-497 25mm Dia. x 175mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 49-497 is a high-quality double-convex lens, designed and manufactured by Edmund Optics, a leading global supplier of optical components. This lens boasts a diameter of 25mm and a focal length of 175mm, making it suitable for a wide range of applications.
The lens is constructed from N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The base shape of the lens is circular, and it features a standard spherical geometry. The radius of curvature for the first surface is 180.4, while the second surface has a radius of curvature of -180.4. The lens has an effective focal length (EFL) of 175mm and a back focal length (BFL) of 173.94mm.
The 49-497 lens is coated with Edmund Optics' NIR I standard curve coating on both the front and back surfaces. This coating is specifically designed for use in the near-infrared region, providing high transmission in the 600-1050nm wavelength range. The coating also offers excellent environmental resistance, ensuring the lens maintains its performance even in challenging conditions.
