49-535 25.0mm Dia. x -35 FL; NIR I Coated; Plano-Concave Lens 600-1050nm
This is a 25.0mm diameter Plano-Concave Lens, offering a focal length of -35 and a base shape of Circular. The lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock. It is designed for use within the wavelength range of 600-1050nm, making it suitable for near-infrared applications.
The lens is made from n-sf11 Schott, a high-index glass with excellent transmittance in the NIR region. It has a thickness of 6.36mm at the edge and 3.5mm at the center, providing a robust structure while maintaining a sleek profile. The inner and outer radii are both 0, indicating a uniform curvature throughout the lens.
The lens features a standard EDMM NIR-I coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the near-infrared spectrum, providing improved transmission and reduced reflection. The coating curve is the standard EDMM NIR-I curve, ensuring consistent performance across similar products.
