14-994 75 mm Dia. N-SF5 Precision Aspheric Lens; EFL=60mm; NA=0.63 Uncoated

This is the 14-994 model from Edmund Optics, a 75 mm diameter N-SF5 precision aspheric lens with an effective focal length (EFL) of 60mm and a numerical aperture (NA) of 0.63, delivered uncoated.

The lens is made of N-SF5 Schott, a high-refractive-index glass that is often used in high-performance optical systems. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional spherical lenses, thereby improving the overall image quality.

The lens has a large NA, which allows for a wide angle of view and high light-gathering capability. The uncoated version of the lens is more cost-effective, but it may have lower transmission and higher reflectivity compared to coated versions.

The geometry of the lens includes an inner radius of 0, an outer radius of 0, a thickness at the edge of 4.73mm, and a thickness at the center of 23.8mm. The lens has a base shape of circle, and the shape is aspheric.

The lens is in stock and available for purchase at the time of this writing, as indicated by its weblink status. For more information and to make a purchase, users can visit the provided weblink.
