G311712000 31.5 mm Dia. UVFS Double-Convex Lens; EFL=40mm Uncoated
The G311712000 is a 31.5 mm diameter double-convex lens, manufactured by Qioptiq Photonics. This lens is designed for use with a wavelength of 355 nm and is uncoated. The lens features a symmetric convex-convex design, making it suitable for a wide range of optical applications.
The lens has an effective focal length (EFL) of 40 mm, which is the distance from the lens's center to the focal point when the lens is focused at infinity. The lens's geometry includes a thickness of 2 mm at the edge and 8.6 mm at the center. The radii of curvature for the first and second surfaces are 39.243 mm and -39.243 mm, respectively.
The lens is made from UVFS (mal- 1965), a material known for its excellent optical properties. The material's refractive index and Abbe number contribute to the lens's high-quality performance. The lens's shape is spherical, which is a common choice for applications requiring a wide field of view.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may result in a lower transmission rate and increased susceptibility to environmental factors, it also means the lens is less likely to introduce chromatic aberrations.
