16-952 12.5mm Dia. N-SF6 Precision Aspheric Lens; EFL=12.5mm; NA=0.5 VIS-EXT Plus 350-700nm

The 16-952 is a high-precision aspheric lens, boasting a 12.5mm diameter and a numerical aperture (NA) of 0.5. This lens is designed to work within the visible light spectrum, specifically between 350-700nm. The lens is crafted from n-SF6 Schott, a high-quality optical material known for its excellent transmission properties and durability.

The lens features a focal length (EFL) of 12.5mm, which is the distance from the lens's principal point to the point where it focuses light. This makes it ideal for applications that require a tight focus of light, such as microscopy or beam shaping. The lens also has a high NA, which allows for a larger acceptance angle of incoming light, thereby increasing the light-gathering capability of the lens.

The 16-952 lens has a precise aspheric shape, which helps to correct spherical aberration, a common issue in traditional lenses. This results in improved image quality and increased design flexibility. The lens also features a thick edge (5.5mm) and a center thickness of 7.5mm, providing robustness and stability.

The lens is coated with Edmund Optics' VIS-EXT Plus coating, which is designed for 350-700nm applications. This coating enhances the lens's transmission properties, reduces surface reflections, and protects the lens from environmental hazards.
