49-516 6.0mm Dia. x -6 FL; NIR I Coated; Plano-Concave Lens 600-1050nm
The 49-516 is a 60mm diameter Plano-Concave Lens with a focal length of -6, sourced from the reputable optical vendor, 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 planar front surface and a concave rear surface. The diameter of the lens is 6mm, and it has a center thickness of 1.5mm and an edge thickness of 2.35mm.
The 49-516 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 in the NIR region, improving its transmission and reducing reflections. The coating status is currently in stock, according to the vendor's website.
