49-534 25.0mm Dia. x -25 FL; NIR I Coated; Plano-Concave Lens 600-1050nm
This is a 25.0mm diameter Plano-Concave Lens, offering a focal length of -25 and a central thickness of 3.5. The lens is sourced from Edmund Optics, a reputable vendor in the optical industry. It is designed for use within the near-infrared spectrum, specifically between 600-1050nm, making it suitable for a wide range of applications in this region.
The lens is constructed from n-sf11 Schott, a high-index glass material known for its excellent optical properties. This includes a high Abbe number, which contributes to low chromatic dispersion, and a high refractive index, which allows for more compact optical designs. The lens has an edge thickness of 7.41mm, providing robustness and durability.
The lens features a standard NIR I coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the near-infrared region, improving transmission and reducing reflection. The coating curve is the standard curve provided by Edmund Optics, ensuring consistent performance across their product range.
