48-781 25.0mm Dia. x 750.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 48-781 is a Plano-Convex Spherical Lens, sourced from Edmund Optics, offering a diameter of 25.0mm and a focal length of 750.0mm. This lens is specifically designed for use within the near-infrared spectrum, catering to wavelengths between 600-1050nm.
The lens's geometry is characterized by a 3.0mm edge thickness and a 3.2mm center thickness, with an effective focal length (EFL) of 750mm. The front surface radius (R1) is 387.6mm, and the back focal length (BFL) measures 747.89mm. The lens's inner and outer radii are both zero, indicating a uniform curvature throughout.
The lens is constructed from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion. This material is well-suited for a wide range of optical applications, particularly those involving broadband or laser light.
The lens features a standard NIR I coating on both the front and back surfaces. This coating is specifically designed to enhance performance within the near-infrared spectrum, providing improved transmission and reduced reflection. The coating status is currently in stock, ensuring prompt availability for your optical needs.
