L-QPX027 25 mm Dia. UVFS Plano-Convex Lens; EFL=250mm Uncoated

The L-QPX027 is a 25 mm diameter Plano-Convex lens, sourced from the renowned optical component vendor, Ross Optical. This lens is designed for use in the ultraviolet-visible-near infrared (UV-VIS-NIR) spectrum, specifically at a wavelength of 587.6 nm.

The lens is made from UVFS (UV Fused Silica) material, identified as 'UVFS MAL-1965' in the material database. This material is known for its excellent transparency across a wide spectral range, making it suitable for various optical applications.

The lens geometry features a plano-convex design, where one side is flat (plano) and the other side is curved (convex). The curvature radius (R1) is 114.6 mm, and the back focal length (BFL) is 249 mm. The effective focal length (EFL) is 250 mm, which is the distance from the lens's principal point to the focal point where light rays converge.

The lens has a center thickness of 2.7 mm and an edge thickness of 2 mm. The inner and outer radii are both 0 mm, indicating that the lens's curved surface is uniformly curved from the center to the edge.

Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing surface reflections, increasing transmission, or providing protection against environmental factors. However, this lens is designed to function without these enhancements, offering a more cost-effective solution for certain applications.
