G311713400 31.5 mm Dia. UVFS Double-Convex Lens; EFL=50mm
The G311713400 is a 31.5 mm diameter double-convex lens, designed for use in ultraviolet applications with a wavelength of 355 nm. This lens is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics.
The lens features a symmetric convex-convex design, with both faces of the lens curved outwards. The first radius of curvature (R1) is 49.594 mm, while the second radius of curvature (R2) is also -49.594 mm, indicating a high degree of symmetry. This design results in an effective focal length (EFL) of 50 mm, making it suitable for a wide range of optical applications.
The lens is made from UVFS (Ultra-Violet Fused Silica) material, identified as "UVFS mal- 1965" in the item data. This material is known for its excellent transparency in the ultraviolet region, making it ideal for use in UV applications.
The lens has a thickness of 2.2 mm at the edge and 7.3 mm at the center. The inner and outer radii are both 0 mm, indicating that the lens is a simple double-convex design without any additional features such as threads or mounts.
The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces. This coating is designed to enhance the lens's performance in the ultraviolet region, providing improved transmission and reduced reflectance.
