G311204000 12.5 mm Dia. UVFS Double-Convex Lens; EFL=12.5mm Uncoated
The G311204000 is a 12.5 mm diameter double-convex lens, manufactured by Qioptiq Photonics. This lens, designed for use in the ultraviolet spectrum at a wavelength of 355 nm, is made from UVFS (UV Fused Silica) material, identified as "uvfs mal- 1965".
The lens features a large diameter to thickness ratio, with a thickness of 1 mm at the edge and 4.7 mm at the center. The effective focal length (EFL) is 12.5 mm, and the radii of curvature for the first and second surfaces are 11.548 mm and -11.548 mm respectively. The lens does not have any coating, as indicated in the item data.
This lens is suitable for applications that require a high level of precision and clarity in the ultraviolet spectrum. The double-convex design provides a wide field of view and low distortion, making it ideal for imaging applications. The uncoated surface allows for high transmission of UV light, but may require additional considerations for applications involving high power or high intensity light sources.
