This is the 33-952 model from Edmund Optics, a 15mm Dia. UVFS Aspheric Lens with an effective focal length (EFL) of 25mm and a numerical aperture (NA) of 0.3. The lens is designed for use with UV light, specifically within the wavelength range of 250-425nm.
The lens is made from HPFS7980 Corning, a high-performance fused silica material known for its excellent transmission properties and durability. The aspheric design of the lens helps to reduce spherical aberration, providing sharper images and improved optical performance.
The lens has a thickness of 1.79mm at the edge and 4.36mm at the center. The inner and outer radii are 0mm, and the front diameter is 15mm. The back focal length (BFL) is 22.01mm. The lens is coated with a UV coating (250-425nm) on both the front and back surfaces to enhance its UV transmission properties.
