This is the G312304331 model from Qioptiq Photonics, a 22.4 mm diameter Plano-Convex lens made of UVFS material with an effective focal length (EFL) of 200mm. The lens is unmounted and features a fused silica construction, which is known for its excellent optical transmission and resistance to thermal shock.
The lens's geometry includes a 1.5mm thickness at the edge and a 2.1mm thickness at the center. The front surface has a radius of curvature (RoC) of 100mm, while the back surface is planar. The lens's design is spherical, ensuring high-quality imaging and light transmission.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating reduces surface reflections and increases light transmission, making it suitable for use in high-power laser applications.
The lens is currently in stock and available for purchase on the Qioptiq Photonics website. For more detailed specifications and purchasing information, please refer to the provided weblink.
