This is the G063318331 lens, a high-quality optical component from Qioptiq Photonics. It is a spherical lens with a base shape of a circle, specifically designed for precision optics applications. The lens has a diameter of 22.4 mm and is mounted on UVFS (Ultra-Violet Fused Silica).
The lens features a double-convex geometry, with the first radius of curvature (R1) being 39.525 mm and the second radius (R2) also being -39.525 mm. This geometry gives the lens an effective focal length (EFL) of 40 mm. The edge thickness of the lens is 1.7 mm, while the center thickness is 4.9 mm, providing excellent optical performance.
The lens is made from UVFS material with a Mal-1965 ID. It is designed to work with a wavelength of 355 nm, making it suitable for ultraviolet applications. The lens is coated on both the front and back with Qio AL RALVIS AOI 45, enhancing its durability and performance in its intended application.
The lens is currently in stock and available for purchase on the Qioptiq Photonics website. For more information, you can refer to the provided weblink.
