16-995 20mm Dia. N-SF5 Precision Aspheric Lens; EFL=20mm; NA=0.5 SWIR-Plus 900-1700nm

The 16-995 is a high-precision aspheric lens offered by Edmund Optics, designed for use in the shortwave infrared (SWIR) spectrum, specifically between 900 and 1700nm. This lens boasts a 20mm effective focal length (EFL), making it suitable for a variety of applications that require a compact, high-performance optical component.

The lens is constructed from N-SF5 Schott glass, a material known for its excellent transmission properties in the SWIR range. The aspheric design of the lens helps to minimize spherical aberration, a common issue in traditional spherical lenses, thereby improving the overall image quality.

The lens has a 20mm diameter and a thickness of 7.23mm at the edge, reducing its weight while maintaining its structural integrity. The center thickness is 11.2mm, providing sufficient rigidity for most applications. The numerical aperture (NA) of the lens is 0.5, indicating a wide acceptance angle and high light-gathering capability.

The lens is coated with Edmund Optics' SWIR-Plus coating, which is specifically designed for the 900-1700nm range. This coating enhances the lens's transmission capabilities, reduces surface reflections, and protects the lens from environmental hazards.
