G311718000 31.5 mm Dia. UVFS Double-Convex Lens; EFL=120mm Uncoated

The G311718000 is a 31.5 mm diameter double-convex lens, manufactured by Qioptiq Photonics. This lens is designed for use with a wavelength of 355 nanometers and is made from UVFS material, specifically identified as UVFS MAL-1965.

The lens features a large effective focal length (EFL) of 120mm, making it suitable for applications that require a longer focal length. The double-convex design, characterized by two spherical surfaces that curve outwards, provides a symmetrical curvature. This design can help to minimize spherical aberration, a common optical issue that can lead to distorted or blurred images.

The lens has a thickness of 2.1mm at the edge and 4.1mm at the center. The inner and outer radii are both 0, indicating a symmetrical design. The first radius of curvature (R1) is 121.446mm, while the second radius of curvature (R2) is -121.446mm.

The lens is uncoated, meaning it does not have any additional layers to protect it or enhance its optical properties. This may make it more susceptible to environmental factors such as dust, dirt, or moisture, and it may not perform as well in high-intensity light conditions. However, uncoated lenses can be more cost-effective and are often chosen for applications where such factors are not a concern.

The lens is currently in stock and available for purchase. More information, including pricing and shipping details, can be found on the Qioptiq Photonics website.
