This is the G052122000 12.5 mm Dia. UVFS Mounted Plano-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. This lens, with a focal length of 20mm (EFL), is designed for use in a variety of applications that require precision optics.
The lens is spherical in shape, with a base shape of a circle. It has a diameter of 12.5 mm and a thickness at the edge of 1.3 mm, while the center thickness is 3.5 mm. The lens is made from UVFS material, specifically identified as "UVFS mal- 1965". This material is well-suited for applications involving ultraviolet light, given its specified wavelength of 355 nm.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This may be suitable for applications where such coatings are not necessary or desirable.
The lens is mounted, which means it is already equipped with a suitable mechanism for integration into an optical system. This can save time and effort in the assembly process.
