49-525 12.0mm Dia. x -12 FL; NIR I Coated; Plano-Concave Lens 600-1050nm
This is a 12.0mm diameter Plano-Concave Lens, model 49-525, sourced from Edmund Optics. The lens is designed for use in the near-infrared (NIR) spectrum, specifically for wavelengths between 600nm and 1050nm.
The lens features a concave shape with a base shape of a circle. The center thickness of the lens is 2.2mm, while the edge thickness is 4.12mm. The effective focal length (EFL) of the lens is -12mm, making it a powerful tool for focusing or diverging light in NIR applications.
The lens is made from n-sf11 Schott glass, a material known for its excellent optical properties in the NIR spectrum. It is coated with EDM NIR-I std curve on both the front and back surfaces, enhancing its performance in the NIR range.
This lens is a Spherical Lens, meaning it has a spherical surface, which is the simplest type of lens surface. The inner and outer radii of the lens are 0, indicating a uniform curvature across the lens surface.
The lens is in stock and available for immediate purchase from the Edmund Optics website, as indicated by the "weblink status" field in the item data.
