The G312301331 is a plano-convex lens with a diameter of 22.4 mm, sourced from Qioptiq Photonics. This lens is designed for use with a wavelength of 355 nm and is made from UVFS material, identified as "uvfs mal- 1965". The lens features a focal length of 60 mm (EFL), making it suitable for a variety of applications.
The lens's geometry includes a thickness of 1.6 mm at the edge and 3.7 mm at the center. The front surface has a radius of curvature of 30.287 mm, while the back surface is planar. The lens does not have any inner or outer radius specified, indicating that it is a simple plano-convex design.
The lens is coated with "qio al ralvis aoi 45" on both the front and back surfaces, which is likely a type of anti-reflective coating designed to reduce losses and improve transmission at the specified wavelength. The lens's shape is spherical, which is typical for plano-convex lenses.
