G311194000 40 mm Dia. UVFS Double-Convex Lens; EFL=125mm Uncoated

The G311194000 is a 40 mm diameter double-convex lens, manufactured by Qioptiq Photonics. This lens, designed for use with a wavelength of 355 nm, features an effective focal length (EFL) of 125 mm, making it suitable for a range of applications that require precise focusing.

The lens is made from UVFS (mal- 1965), a material known for its excellent optical properties, particularly in the ultraviolet spectrum. The base shape of the lens is circular, and it has a center thickness of 5 mm and an edge thickness of 1.8 mm. The radii of curvature for the first and second surfaces are 114.735405 mm and -114.735405 mm respectively, indicating a symmetric convex-convex design.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain situations. For instance, uncoated lenses can be more cost-effective and are often more resistant to damage from environmental factors.
