49-998 9mm Dia. x 36mm FL; VIS 0deg Coated; UV Double-Convex Lens VIS 0deg 425-675nm
The 49-998 is a high-quality spherical lens, boasting a 9mm diameter and a 36mm focal length, making it a versatile choice for various optical applications. This lens is sourced from the reputable vendor, Edmund Optics, ensuring reliability and performance.
The lens is designed with a double-convex geometry, featuring a 32.69mm radius of curvature on both sides. This design allows for a broad range of wavelengths to be focused, spanning from 425nm to 675nm in the visible spectrum. The lens has a center thickness of 2mm and an edge thickness of 1.38mm, providing robustness and durability.
The 49-998 lens is fabricated from fused silica (mal-1965), a material known for its excellent optical properties, including high transparency and resistance to thermal shock. This makes the lens suitable for use in harsh environments and applications requiring high precision.
The lens surfaces are coated with a standard VIS-0 coating, which is optimized for 0-degree incidence angle. This coating enhances the lens's performance by reducing surface reflections and improving transmission, thereby increasing the overall efficiency of the optical system.
