63-820 6mm Dia. x 18mm FL; VIS-NIR Coated; UV Double-Convex Lens VIS-NIR 400-1000nm
The 63-820 is a high-quality spherical lens, boasting a 6mm diameter and a focal length of 18mm. This lens is sourced from the reputable vendor, Edmund Optics, and is available for purchase on their website. The lens is currently in stock, ready for immediate use.
The lens is designed with a double-convex geometry, featuring a curvature radius of 16.18mm on both sides. This design ensures a high level of light concentration, making it ideal for a wide range of applications. The lens has a central thickness of 2mm and an edge thickness of 1.44mm, providing a robust structure while maintaining a compact form factor.
The lens is crafted from fused silica, a material with a high transparency range and excellent thermal stability. This makes it suitable for use in the visible and near-infrared spectrum, specifically between 400 and 1000nm. The lens is coated with a VIS-NIR coating on both the front and back surfaces, further enhancing its performance in this spectrum. The coating, identified as edm visnir0sp2002000, provides superior anti-reflection properties, reducing losses and improving transmission.
