16-963 30mm Dia. N-SF5 Precision Aspheric Lens; EFL=30mm; NA=0.5 VIS-EXT Plus 350-700nm

This is the 16-963 model from Edmund Optics, a high-precision aspheric lens with a 30mm diameter and a numerical aperture of 0.5. The lens is designed for use within the visible light spectrum, specifically between 350-700nm.

The lens is made from N-SF5 Schott, a high-refractive index glass that is often used in optical applications requiring high performance. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional spherical lenses, resulting in improved image quality and resolution.

The lens has an effective focal length (EFL) of 30mm, which is the distance from the center of the lens to the point at which light rays converge. This makes the lens suitable for use in a variety of applications, including imaging systems, beam shaping, and laser applications.

The lens has a center thickness of 12.5mm and an edge thickness of 6.59mm, providing structural integrity and durability. The front and back surfaces of the lens are coated with Edmund Optics' VIS-EXT Plus coating, which is designed to enhance transmission in the 350-700nm range. This coating also provides protection against environmental factors such as dust, moisture, and scratches.
