This Qioptiq Photonics lens, identified as G312302400, is a 22.4 mm diameter Plano-Convex spherical lens, designed for use in the ultraviolet spectrum at a wavelength of 355 nm. The lens is unmounted and made from UVFS material, specifically UVFS Mal-1965, which is known for its excellent transmission properties in the UV range.
The lens has an effective focal length (EFL) of 80 mm, making it suitable for applications that require moderate magnification and a relatively long working distance. The lens's geometry includes a 1.5 mm thickness at the edge, increasing to 3.1 mm at the center, providing a solid structure while maintaining a reasonable weight.
The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces, which enhances its reflectivity and durability. This coating is particularly beneficial in UV applications, where maintaining high transmission and reducing scatter are crucial.
Please note that the inner and outer radii of the lens are 0, indicating a simple Plano-Convex design without any additional curvature or features. This design is often chosen for its simplicity, wide field of view, and low distortion.
