38-499 12.5mm Dia. x 12.5mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 38-499 is a Plano-Convex lens with a diameter of 12.5mm and a focal length of 12.5mm, sourced from the reputable optical vendor, Edmund Optics. This lens is designed for use within the visible to near-infrared spectrum, specifically catering to wavelengths between 400nm and 1000nm.
The lens is constructed from n-SF11 Schott, a high-index glass with excellent optical properties. The Plano-Convex geometry, where one side is flat and the other is curved, allows for efficient light collection and focusing. The lens has a center thickness of 3.75mm and an edge thickness of 1.5mm, providing robustness and durability.
The lens features a VIS-NIR coating, denoted as 'edm visnir0sp2002000', on both the front and back surfaces. This coating is designed to enhance the lens' performance within the visible to near-infrared spectrum, reducing surface reflections and improving transmission.
The 38-499 is a versatile and high-performing lens, ideal for applications that require precise light manipulation within the specified wavelength range. Its compact size and robust construction make it suitable for integration into various optical systems.
