G311206331 18 mm Dia. UVFS Double-Convex Lens; EFL=20mm
The G311206331 is a high-quality spherical lens from Qioptiq Photonics, designed for precision optics applications. This lens, with a diameter of 18 mm, is a symmetric convex-convex lens, also known as a double-convex lens, which means it has two convex surfaces.
The lens has an effective focal length (EFL) of 20 mm, which is the distance from the lens's center to the focal point when the lens is focused at infinity. This makes it suitable for applications that require a moderate level of magnification.
The lens's geometry includes a thickness of 1.4 mm at the edge and 5.8 mm at the center. The radii of curvature for the first and second surfaces are 19.668 mm and -19.668 mm, respectively. The lens is made from UVFS material with the Mal-1965 ID, and it is designed to work with a wavelength of 355 nm.
The lens features a Qio AL RALVIS AOI 45 coating on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, enhancing the lens's performance in demanding optical applications.
The item data also indicates that this lens is in stock and available for immediate purchase, making it an ideal choice for users who need a reliable and high-performance lens for their optical systems.
