G313333331 22.4 mm Dia. UVFS Double-Concave Lens; EFL=-50mm
This is the G313333331 model from Qioptiq Photonics, a 22.4 mm diameter UVFS Double-Concave Lens with an effective focal length (EFL) of -50mm. The lens is made of UVFS material with the Mal-1965 ID, specifically designed for use at a wavelength of 355nm.
The lens features a unique double-concave geometry, with both surfaces curved inward. The first surface has a radius of curvature (R1) of -50.481mm, while the second surface has an R2 of 50.481mm. The lens has a center thickness of 1.5mm. The inner and outer radii are both 0mm, indicating a symmetrical design.
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, making it ideal for various applications.
The lens is available from the Qioptiq shop and is currently in stock. For more information, you can visit the provided weblink.
