48-346 9mm Dia. x -12 FL; VIS-NIR Coated; Plano-Concave Lens 400-1000nm

The 48-346 is a Plano-Concave Lens with a 9mm diameter, offering a -12 FL (focal length) and a -9.42 mm radius of curvature (RoC) on the front surface. The lens is sourced from Edmund Optics, a reputable vendor in the optical industry. It is made from n-sf11 Schott, a high-index glass with excellent optical properties, making it suitable for a wide range of applications.

The lens features a plano-concave geometry, meaning it has a flat front surface and a curved back surface. The back surface has a -13.26 mm BFL (back focal length) and a 0 mm inner radius, with the outer radius also being 0 mm. The lens has a center thickness of 2.25 mm and an edge thickness of 3.24 mm, providing robustness and durability.

The 48-346 lens is coated with edm visnir0sp2002000 on both the front and back surfaces. This VIS-NIR coating is designed for the 400-1000nm wavelength range, ensuring high transmission and low reflectance across the visible and near-infrared spectra. This makes the lens ideal for applications that require high-quality imaging or light transmission in this wavelength range.
