49-522 9.0mm Dia. x -12 FL; NIR I Coated; Plano-Concave Lens 600-1050nm

The 49-522 is a 9.0mm diameter Plano-Concave Lens with a focal length of -12, sourced from Edmund Optics. This lens is designed for use within the near-infrared spectrum, specifically between 600-1050nm, making it suitable for a wide range of applications in this wavelength range.

The lens is constructed from n-sf11 Schott, a high-index glass with excellent transmittance in the NIR region. The base shape of the lens is circular, and it features a plano-concave geometry, meaning one side is flat while the other is curved inward. This particular lens has an inner radius of 0 and an outer radius of 0, indicating a uniform curvature across its surface.

The 49-522 lens has a thickness of 3.24mm at the edge and 2.25mm at the center. The back focal length (BFL) is -13.26mm, and the effective focal length (EFL) is -12mm. The front and back surfaces of the lens are coated with Edmund Optics' NIR I standard curve coating, which is designed to enhance the lens' performance in the near-infrared spectrum.

This lens is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. With its high-quality construction, specific NIR coating, and plano-concave geometry, the 49-522 is an excellent choice for any application that requires a lens in the 600-1050nm range.
