16-962 25mm Dia. N-SF6 Precision Aspheric Lens; EFL=15mm; NA=0.83 VIS-EXT Plus 350-700nm
The 16-962 is a high-precision aspheric lens offered by Edmund Optics, boasting a 25mm diameter and a numerical aperture of 0.83. This lens is designed for use within the visible light spectrum, specifically between 350 and 700nm.
The lens is constructed from N-SF6 Schott glass, a material known for its excellent optical properties and durability. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional lenses, resulting in improved image quality and resolution.
The lens features an effective focal length of 15mm, making it suitable for a variety of applications where compactness and high performance are required. The front and back surfaces of the lens are coated with Edmund Optics' VIS-EXT Plus coating, which enhances transmission within the specified wavelength range and provides excellent environmental resistance.
The lens has a center thickness of 10.4mm and an edge thickness of 3.31mm, contributing to its robustness and structural integrity. The front and back focal lengths are 2.562558e-06mm and -2.398087e-08mm, respectively. The lens's shape is defined by its inner and outer radii, both of which are 0mm, and its conic constant, k1, which is -0.6243706.
