16-988 40mm Dia. N-SF6 Precision Aspheric Lens; EFL=25mm; NA=0.8 NIR-Plus 600-1050nm

The 16-988 is a high-precision aspheric lens, designed and manufactured by Edmund Optics. This lens boasts a 40mm diameter and a 0.8 numerical aperture (NA), making it an ideal choice for applications that require a wide field of view and high light-gathering capability.

The lens is made from N-SF6 Schott glass, a material known for its excellent optical properties in the near-infrared (NIR) region. The NIR-Plus coating, applied to both the front and back surfaces, further enhances the lens' performance in the 600-1050nm wavelength range. This coating reduces surface reflections, improving transmission and contrast, and increasing the lens' overall efficiency.

The lens' geometry is optimized for superior optical performance. It features a 25mm effective focal length (EFL), a 2.4mm thickness at the edge, and a 13.1mm thickness at the center. The aspheric design corrects spherical aberration, a common issue in traditional lenses, resulting in sharper images with increased resolution and contrast.
