16-293 15mm Dia. S-LAH64 NIR Aspheric Lens; EFL=12mm; NA=0.63 SWIR-Plus 900-1700nm
The 16-293 15mm Dia. S-LAH64 NIR Aspheric Lens is a high-quality optical component designed for use in the near-infrared (NIR) spectrum, specifically between 900 and 1700nm. This lens, sourced from Edmund Optics, is a precision aspheric lens, offering superior performance over traditional spherical lenses.
The lens features a 15mm diameter and a numerical aperture (NA) of 0.63, providing a high level of light-gathering capability. The effective focal length (EFL) of this lens is 12mm, making it suitable for a variety of applications where compactness and high performance are required.
The lens is made from S-LAH64, a high-refractive index material from Ohara, which allows for excellent optical performance. The lens geometry includes a range of parameters, such as a 9.32mm radius of curvature (R1), a 0mm radius of curvature (R2), and a 9.02mm back focal length (BFL). The center thickness of the lens is 5.28mm, while the edge thickness is 2.09mm.
The lens is coated with Edmund Optics' SWIR-Plus coating, designed for the 900-1700nm range. This coating enhances the lens's performance in the NIR spectrum, providing improved transmission and reduced reflectance. The coating is applied to both the front and back surfaces of the lens.
