G063161000 31.5 mm Dia. UVFS Mounted Double-Convex Lens; EFL=30mm Uncoated

This is the G063161000, a 31.5 mm diameter UVFS mounted double-convex lens with an effective focal length (EFL) of 30mm, sourced from Qioptiq Photonics. The lens is uncoated, offering a unique set of optical properties.

The lens is a symmetric convex-convex design, meaning it has two spherical surfaces that are both convex, or curved outwards. This shape is often used to converge light rays to a single point, making it ideal for various optical applications. The base shape of the lens is circular, ensuring uniformity in light collection and distribution.

The geometry of the lens is meticulously designed. The edge thickness is 2mm, while the center thickness is 11.5mm, providing a robust structure. The first radius of curvature (R1) is 28.49mm, and the second radius (R2) is -28.49mm, indicating the lens's double-convex nature. The inner and outer radii are 0mm, suggesting a uniform curvature throughout the lens.

The lens is made from UVFS, a material with a high transmission rate in the ultraviolet range, making it suitable for applications using UV light. The material ID is UVFS MAL-1965, providing a clear identifier for this specific material grade.

The lens is designed to operate at a wavelength of 355nm, making it suitable for various applications in this wavelength range. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. This could result in a higher susceptibility to environmental factors and a lower transmission rate compared to coated lenses. However, it may also offer other advantages, such as a lower cost or a simpler manufacturing process.
