16-990 50mm Dia. N-SF6 Precision Aspheric Lens; EFL=30mm; NA=0.83 NIR-Plus 600-1050nm
The 16-990 is a high-precision aspheric lens, boasting a 50mm diameter and a numerical aperture (NA) of 0.83. This lens is designed for use within the near-infrared spectrum, specifically between 600 and 1050nm. The lens is crafted from N-SF6 Schott, a high-quality optical glass known for its excellent transmission properties in the near-infrared region.
The lens features a focal length (EFL) of 30mm, making it suitable for a variety of applications that require a compact, high-performance optical component. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional spherical lenses, resulting in improved image quality and resolution.
The lens has a center thickness of 21.56mm and an edge thickness of 7.35mm, providing robustness and durability. The front and back surfaces of the lens are coated with Edmund Optics' NIR-Plus 600-1050nm coating, which enhances its transmission capabilities within the specified wavelength range.
This lens is currently in stock and available for immediate purchase through the Edmund Optics website. With its high-quality materials, advanced design, and reliable performance, the 16-990 is an excellent choice for a wide range of optical applications.
