22-757 15mm Dia. N-SF6 Precision Aspheric Lens; EFL=9mm; NA=0.83 VIS-EXT Plus 350-700nm

The 22-757 is a high-precision aspheric lens, 15mm in diameter, with a numerical aperture (NA) of 0.83. This lens is designed for use in the visible light spectrum, specifically between 350 and 700nm. The lens is fabricated from N-SF6 Schott glass, a material known for its excellent optical properties and durability.

The lens features an effective focal length (EFL) of 9mm, making it suitable for applications that require a compact, high-performance optical component. The aspheric design of the lens helps to minimize spherical aberration, a common issue in traditional spherical lenses, resulting in improved image quality and resolution.

The lens has a center thickness of 9.7mm and an edge thickness of 5.28mm, providing robustness and resistance to deformation. The front and back surfaces of the lens are coated with Edmund Optics' VIS-EXT coating, which is designed to enhance transmission in the visible spectrum while providing protection against environmental factors such as dust and moisture.

The lens geometry includes a range of parameters, such as inner and outer radii, diameter, thickness edge, EFL, r1, r2, bfl, k1, k2, na, d front, e front, f front, g front, h front, and j front, all of which contribute to the lens's unique optical performance.
