17-329 25mm Dia. UVFS Aspheric Lens; EFL=50mm; NA=0.23 Uncoated
The 17-329 25mm Dia. UVFS Aspheric Lens is a high-quality optical component sourced from Edmund Optics. This lens, with a catalog number of 17-329, is designed for use in ultraviolet applications, specifically at a wavelength of 355nm.
The lens features a base shape of a circle, with a diameter of 25mm. It has a high numerical aperture (NA) of 0.23, which allows for a wide angle of acceptance and increased light-gathering capability. The effective focal length (EFL) of this lens is 50mm, making it suitable for a variety of optical systems.
The lens is made from UV fused silica, a material known for its excellent transparency in the ultraviolet spectrum. This material is identified in the item data as "syn hpfs7980 corning". The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The geometry of the lens includes an inner radius of 0mm, an outer radius of 0mm, a thickness at the edge of 3.82mm, and a thickness at the center of 7.2mm. The front surface of the lens has a conic constant of -0.663, which is a measure of its asphericity.
This lens is available for purchase through the Edmund Optics website, and the link provided in the item data indicates that it is currently in stock.
