17-008 40mm Dia. N-SF5 Precision Aspheric Lens; EFL=40mm; NA=0.5 SWIR-Plus 900-1700nm

The 17-008 is a high-precision aspheric lens, designed and manufactured by Edmund Optics. This lens is characterized by its 40mm diameter and a numerical aperture (NA) of 0.5, specifically engineered for use within the shortwave infrared (SWIR) spectrum, specifically between 900 and 1700nm.

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

The lens has an effective focal length (EFL) of 40mm, which is the distance from the lens's optical center to the point at which the light rays converge. This EFL, combined with the lens's NA, provides a wide field of view and high light-gathering capability, making it suitable for various applications.

The lens features a precision-ground edge thickness of 6.83mm and a center thickness of 14.7mm. The front and back surfaces of the lens are coated with Edmund Optics' SWIR-Plus coating, which enhances the lens's transmission capabilities within the 900-1700nm range.

In terms of geometry, the lens has an inner radius of 0mm, an outer radius of 0mm, and a diameter of 40mm. The front and back focal lengths are 1.1304e-06mm and 2.028051e-10mm, respectively. The lens's conic constant (k1) is -0.763317, and it has a paraxial curvature (r1) of 26.91mm.

The 17-008 lens is available for purchase from Edmund Optics' website, and as of the time of data collection, it is in stock.
