This is the G052123322 model from Qioptiq Photonics, a 12.5 mm diameter Plano-Convex lens with a UVFS mounted design. The lens is specifically designed for use within the wavelength range of 450-700nm, making it suitable for a variety of applications within this spectrum.
The lens features an effective focal length (EFL) of 25mm, which is the distance from the lens's center to the focal point when the lens is focused at infinity. This EFL, combined with the lens's diameter, provides a decent field of view and depth of field, making it suitable for use in imaging systems.
The lens is made from UVFS, a material with a refractive index that is ideal for use within the specified wavelength range. The lens's geometry includes a thickness of 1.3mm at the edge and 3mm at the center, with a radius of curvature of 12.589mm on the curved surface. The lens's design is spherical, which is the simplest and most common type of lens design.
The lens features a broadband anti-reflection coating on both the front and back surfaces. This coating, identified as Qio Bbar Arb2visnbk7, is designed to reduce surface reflections and increase transmission, thereby improving the lens's performance in its intended application.
The lens is mounted, which means it is ready for immediate use in an optical system. This can save time and effort in the assembly process, making it a convenient choice for users.
