This is the G063030400 22.4 mm Dia. UVFS Mounted Double-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens, with a clear aperture of 22.4 mm, is designed for use in systems with a wavelength of 355 nm.
The lens is a symmetric convex-convex design, featuring two convex surfaces with radii of curvature 24.406 mm and -24.406 mm respectively. This shape, combined with the lens's thickness of 1.6 mm at the edge and 7 mm at the center, gives the lens an effective focal length (EFL) of 25 mm.
The lens is made from UVFS material, identified as "UVFS mal- 1965" in the item data. This material is known for its excellent transmittance in the ultraviolet region, making it suitable for applications that require high-performance UV optics.
The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces. This coating is designed to enhance the lens's performance by reducing surface reflections and improving transmission.
The lens is mounted in a fused silica mount, ensuring stability and ease of integration into optical systems. According to the item data, this lens is currently in stock and available for immediate purchase.
