16-980 25mm Dia. N-SF6 Precision Aspheric Lens; EFL=25mm; NA=0.5 NIR-Plus 600-1050nm

The 16-980 is a high-precision aspheric lens, boasting a 25mm diameter and a numerical aperture of 0.5, specifically designed for use in the near-infrared spectrum, between 600 and 1050nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is a part of their extensive catalog.

The lens is constructed from N-SF6 Schott, a high-quality optical glass known for its excellent transmission properties in the near-infrared region. The aspheric design of the lens helps to minimize spherical aberration, providing superior image quality compared to traditional spherical lenses.

The lens has an effective focal length (EFL) of 25mm, making it suitable for a wide range of optical applications. The inner and outer radii of the lens are 0, indicating a circular shape. The lens has a thickness of 5.86mm at the edge and 9.86mm at the center. The back focal length (BFL) is 19.54mm.

The lens is coated with Edmund Optics' NIR-Plus 600-1050nm coating on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared region, improving transmission and reducing reflection.

The item data also provides detailed aspheric geometry information, including the conic constant (k1) and aspheric coefficients (k2, k3, k4, k5, k6). These parameters can be used to precisely model the lens's shape and performance in optical simulations.
