16-982 25mm Dia. N-SF6 Precision Aspheric Lens; EFL=15mm; NA=0.83 NIR-Plus 600-1050nm
The 16-982 is a high-precision aspheric lens, boasting a 25mm diameter and a numerical aperture of 0.83. This lens is designed for use in the near-infrared spectrum, specifically between 600 and 1050nm.
The lens is crafted from N-SF6 Schott, a high-quality optical material known for its excellent transmission properties in the near-infrared region. The aspheric design of the lens helps to reduce spherical aberration, thereby improving the overall image quality.
The lens has an effective focal length of 15mm, making it suitable for use in compact optical systems. The front and back surfaces of the lens are coated with Edmund Optics' NIR-Plus 600-1050nm coating, which enhances the lens's transmission in the near-infrared spectrum.
The lens has a center thickness of 10.4mm and an edge thickness of 3.31mm. The front and back radii of the lens are 12.078mm and 0mm, respectively. The lens's conic constant is -0.6243706, and its aspheric coefficients are k1=-0.6243706, k2=0.
This lens is an excellent choice for applications that require high-quality imaging in the near-infrared spectrum, such as night vision systems, thermal imaging, and spectral analysis.
