16-992 12.5mm Dia. N-SF6 Precision Aspheric Lens; EFL=12.5mm; NA=0.5 SWIR-Plus 900-1700nm

The 16-992 is a high-precision aspheric lens, boasting a 12.5mm diameter and a numerical aperture (NA) of 0.5, specifically designed for use in the shortwave infrared (SWIR) spectrum, covering the wavelength range of 900-1700nm. This lens is sourced from the reputable optical vendor, Edmund Optics.

The lens is crafted from N-SF6 Schott, a high-quality optical glass, and features an effective focal length (EFL) of 12.5mm, ensuring a compact and efficient optical system. The lens's geometry includes an inner radius of 0mm, an outer radius of 0mm, a thickness at the edge of 5.5mm, and a thickness at the center of 7.5mm. The front and back surfaces of the lens are coated with Edmund Optics' SWIR-Plus 900-1700nm coating, enhancing its performance in the SWIR spectrum.

The aspheric design of the lens, characterized by its radii (r1: 10.065mm, r2: 0mm), provides superior optical quality, minimizing spherical aberration and delivering sharp, clear images. The lens's conic constant (k1: -0.896905) further contributes to its high-performance capabilities.
