16-290 10mm Dia. S-LAH64 NIR Aspheric Lens; EFL=8mm; NA=0.63 SWIR-Plus 900-1700nm

The 16-290 is a high-performance aspheric lens designed for use in the near-infrared (NIR) spectrum, specifically for wavelengths between 900 and 1700nm. This lens is manufactured by Edmund Optics, a leading provider of optical components, and is available for purchase through their online catalog.

The lens features a 10mm diameter and a numerical aperture (NA) of 0.63, making it suitable for a wide range of applications that require high light-gathering capabilities and sharp image resolution. The aspheric design of the lens helps to minimize spherical aberration, a common issue in traditional spherical lenses, resulting in improved image quality and reduced distortion.

The lens is made from S-LAH64, a high-quality optical glass from Ohara, which is known for its excellent transmittance and low autofluorescence in the NIR spectrum. This makes the 16-290 an ideal choice for applications such as hyperspectral imaging, night vision, and scientific research.

The lens is coated with Edmund Optics' SWIR-Plus coating, which is specifically designed for use in the short-wave infrared (SWIR) region. This coating enhances the lens's transmission capabilities, reduces surface reflections, and protects the lens from environmental hazards, ensuring long-lasting performance and durability.

The 16-290 has an effective focal length (EFL) of 8mm, which, combined with its high NA, makes it a versatile lens suitable for both wide-angle and telephoto applications. The lens also features a robust design with a 1.57mm thickness at the edge and a 3.7mm thickness at the center, providing excellent mechanical stability and resistance to stress and deformation.
