63-824 9mm Dia. x 18mm FL; VIS-NIR Coated; UV Double-Convex Lens VIS-NIR 400-1000nm
The 63-824 is a high-quality spherical lens, boasting a 9mm diameter and a focal length of 18mm, sourced from the reputable vendor, Edmund Optics. This lens is designed for use within the visible to near-infrared spectrum (VIS-NIR), specifically catering to wavelengths between 400-1000nm.
The lens features a unique double-convex shape, characterized by its base shape being circular and having two convex surfaces (r1: 16.09, r2: -16.09). This design provides excellent optical performance and a broad range of applications. The lens's edge thickness measures 1.32mm, while its center thickness is 2.6mm, ensuring robustness and durability.
The 63-824 lens is crafted from fused silica (mal-1965), a material renowned for its exceptional transparency and resistance to thermal shock. This makes the lens suitable for use in various demanding environments.
A key feature of this lens is its VIS-NIR coating, applied to both the front and back surfaces (edm visnir0sp2002000). This specialized coating enhances the lens's performance within the VIS-NIR spectrum, reducing surface reflections and increasing transmission.
