17-330 25mm Dia. UVFS Aspheric Lens; EFL=75mm; NA=0.15 Uncoated

The 17-330 is a 25mm diameter Aspheric Lens, designed for use in ultraviolet light applications with a wavelength of 355nm. This lens is sourced from Edmund Optics, a leading vendor in the optical industry, and is uncoated.

The lens features a high-quality UV fused silica material (syn hpfs7980 corning), ensuring durability and reliability in demanding environments. The base shape of the lens is circular, with an inner radius of 0mm and an outer radius of 0mm. The lens has a thickness of 3.78mm at the edge and 6mm at the center.

The effective focal length (EFL) of the lens is 75mm, making it suitable for medium-range applications. The numerical aperture (NA) is 0.15, indicating a moderate light-gathering capability. The lens has a high-precision asphere with a conic constant of -0.668 and a second-order aspheric coefficient of 0.

The lens is designed to be used without any coating, which can be beneficial in certain applications where coating might introduce unwanted reflections or alter the spectral properties of the light. However, users should be aware that uncoated lenses can be more susceptible to dirt and contamination, and may require more frequent cleaning.
