G311213322 22.4 mm Dia. UVFS Double-Convex Lens; EFL=200mm
The G311213322 is a 22.4 mm diameter double-convex lens, designed for use in ultraviolet applications with a wavelength of 355 nm. This lens, sourced from Qioptiq Photonics, is a spherical lens with a symmetric convex-convex design, providing a high degree of focusing power.
The lens features an effective focal length (EFL) of 200mm, determined by the curvature of its surfaces. The first surface has a radius of curvature (R1) of 199.53mm, while the second surface (R2) has a radius of curvature of -199.53mm. This design results in a lens with a high degree of optical power, making it suitable for a wide range of applications.
The lens is made from UVFS, a type of fused silica, which is known for its excellent optical properties and resistance to thermal shock. The lens has a thickness of 1.6mm at the edge and 2.2mm at the center, providing a robust and durable construction.
The G311213322 is coated with Qio Bbar Arb2visnbk7 on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, enhancing the performance of the lens in its intended application.
