49-264 6mm Dia. x 12mm FL; VIS 0deg Coated; UV Double-Convex Lens VIS 0deg 425-675nm

The 49-264 is a high-quality spherical lens, boasting a 6mm diameter and a 12mm focal length, sourced from the renowned optical vendor, Edmund Optics. This lens is designed for use within the visible light spectrum, specifically catering to the 425-675nm range.

The lens is crafted from fused silica, a material renowned for its exceptional transparency and resistance to thermal shock. This makes it an ideal choice for applications demanding high-performance optical elements. The lens features a double-convex geometry, with radii of curvature of 10.65mm for both the front and rear surfaces, contributing to its impressive optical properties.

The 49-264 lens comes equipped with a standard anti-reflection coating on both the front and rear surfaces, specifically the EDM VIS-0 coating. This coating is designed to minimize surface reflections, thereby enhancing transmission and improving overall system performance. The coating is optimized for a central wavelength of 587.6nm, which is the peak sensitivity of the human eye.

The lens has an effective focal length (EFL) of 12mm, a thickness at the edge of 1.34mm, and a center thickness of 2.2mm. The back focal length (BFL) is 11.23mm. The lens is circular in shape, with no inner or outer radius specified, indicating a full-circle design.
