89-416 5mm Dia x 15mm FL UV-AR Coated; UV Plano-Convex Lens UV-AR 250-425nm
This UV Plano-Convex Lens, model 89-416, is a high-quality optical component sourced from Edmund Optics. It is designed for use in the ultraviolet (UV) spectrum, specifically between 250 and 425 nanometers, making it ideal for applications such as UV curing, fluorescence microscopy, and UV imaging.
The lens features a 5mm diameter and a 15mm focal length (FL), providing a compact yet powerful optical solution. The base shape is circular, and the lens is spherical in geometry, with a 6.88mm radius of curvature (R1) and a 13.83mm back focal length (BFL). The center thickness is 1.7mm, while the edge thickness is 1.23mm, ensuring excellent optical performance and durability.
The lens is made from fused silica (mal-1965), a material known for its high transparency in the UV range and excellent thermal stability. This material also has a low coefficient of thermal expansion, making it resistant to thermal shock.
The lens is coated with a UV-AR coating on both the front and back surfaces. This coating is designed to enhance the lens's performance in the UV range by reducing reflection and increasing transmission. The coating curve is Edmund Optics' standard UV curve, ensuring consistent performance across different components.
