16-993 15mm Dia. N-SF6 Precision Aspheric Lens; EFL=15mm; NA=0.5 SWIR-Plus 900-1700nm
The 16-993 is a high-precision aspheric lens, 15mm in diameter, with a numerical aperture (NA) of 0.5, specifically designed for use in the shortwave infrared (SWIR) spectrum, covering the 900-1700nm range. This lens is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens is made from N-SF6 Schott, a high-refractive index material that is well-suited for infrared applications. It features an effective focal length (EFL) of 15mm, making it a versatile choice for a variety of optical systems. The aspheric design of the lens helps to minimize spherical aberration, enhancing the overall image quality.
The geometry of the lens includes an inner radius of 0mm, an outer radius of 0mm, a thickness at the edge of 6.21mm, and a thickness at the center of 8.62mm. The front and back surfaces of the lens are coated with Edmund Optics' SWIR-Plus coating, which is optimized for the 900-1700nm range, further improving its performance in the SWIR spectrum.
