G052315331 12.7 mm Dia. UVFS Mounted Plano-Concave Lens; EFL=-20mm
This is the G052315331 model from Qioptiq Photonics, a 12.7 mm diameter Plano-Concave Lens with a mounted fused silica. The lens is designed with a negative focal length (EFL) of -20mm, making it suitable for a variety of applications that require light convergence.
The lens is made of UVFS material, specifically identified as "UVFS mal- 1965" in the item data. This material is known for its excellent transmission properties in the ultraviolet, visible, and near-infrared regions, making it a versatile choice for many optical systems.
The lens's geometry is characterized by its spherical shape, with a center thickness of 4mm. The inner and outer radii are both zero, indicating a simple concave shape. The lens's diameter is 12.7mm, providing a decent light gathering capability while maintaining a compact form factor.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.
The lens is mounted, which adds to its convenience and ease of use. It is currently in stock and can be purchased from the vendor's website, as indicated in the item data.
