17-331 25mm Dia. UVFS Aspheric Lens; EFL=75mm; NA=0.15 Uncoated

The 17-331 25mm Dia. UVFS Aspheric Lens is a high-quality optical component designed for use in a variety of applications. Sourced from the reputable vendor Edmund Optics, this lens is characterized by its uncoated UV fused silica aspheric design, which offers a number of advantages over traditional spherical lenses.

The lens features a 25mm diameter and a numerical aperture (NA) of 0.15, making it suitable for use with a wide range of wavelengths, including 355nm. The aspheric design of the lens helps to reduce spherical aberration, improving image quality and resolution. The lens has an effective focal length (EFL) of 75mm, which, combined with its NA, gives it a relatively high optical power.

The lens is made from high-purity fused silica, which offers excellent transmission across a wide spectral range and is highly resistant to thermal shock and chemical etching. The uncoated design of the lens allows for maximum transmission of light, but it may be more susceptible to surface reflections and scattering than coated lenses.

The geometry of the lens includes an inner radius of 0mm, an outer radius of 0mm, a thickness at the edge of 3.78mm, and a thickness at the center of 6mm. The front surface of the lens has a radius of curvature of 35.707mm, while the back surface is flat. The lens also has a back focal length (BFL) of 70.9mm.
