G311213000 22.4 mm Dia. UVFS Double-Convex Lens; EFL=200mm Uncoated

The G311213000 is a 22.4 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 large effective focal length (EFL) of 200 mm, making it suitable for a variety of applications that require high magnification or long-distance focusing.

The lens is constructed with a symmetric convex-convex design, meaning both sides of the lens are curved outwards. The radii of curvature for the first and second surfaces are 199.53 mm and -199.53 mm, respectively. This specific curvature allows for a high degree of light bending, which can be beneficial in applications where a tight focus is required.

The lens has a center thickness of 2.2 mm and an edge thickness of 1.6 mm. The inner and outer radii are both 0 mm, indicating that the lens is uniformly curved from edge to edge. The lens is made from UVFS (mal- 1965), a material known for its excellent transparency in the ultraviolet region of the spectrum.
