G063344329 22.4 mm Dia. UVFS Mounted Double-Concave Lens; EFL=-20mm 1064nm
This is a G063344329 model double-concave lens, featuring a 22.4 mm diameter and a center thickness of 1.5 mm. The lens is mounted on UVFS (Ultra-Violet Fused Silica) material, identified as "uvfs mal- 1965" in the Material ID. The effective focal length (EFL) of this lens is -20mm, making it a negatively powered lens suitable for specific optical applications.
The lens's geometry includes a first radius (r1) of -20.535mm and a second radius (r2) of 20.535mm, both measured from the lens center. The inner and outer radii are 0mm, indicating a symmetrical concave-concave shape. The lens is designed to operate at a wavelength of 355nm, as specified in the item data.
The lens comes with anti-reflection coatings on both the front and back surfaces. The coating type is "qio hp nbar arhs-yag", which is designed to minimize surface reflections and increase transmission in the near-infrared region, specifically at 1064nm. This coating enhances the lens performance in its intended application.
