16-960 25mm Dia. N-SF6 Precision Aspheric Lens; EFL=25mm; NA=0.5 VIS-EXT Plus 350-700nm
The 16-960 is a high-precision aspheric lens offered by Edmund Optics, boasting a 25mm diameter and a numerical aperture of 0.5. This lens is designed for use within the visible light spectrum, specifically between 350-700nm, making it suitable for a wide range of optical applications.
The lens is constructed from n-SF6 Schott, a high-quality optical material known for its excellent transmission properties and chemical resistance. The aspheric design of the lens helps to reduce spherical aberration, enhancing the overall image quality and resolution.
The geometry of the lens includes an inner radius of 0mm, an outer radius of 0mm, a thickness at the edge of 5.86mm, and an effective focal length (EFL) of 25mm. The lens's front radius (r1) is 20.13mm, while the back radius (r2) is 0mm. The back focal length (BFL) is 19.54mm, and the thickness at the center is 9.86mm.
The lens features a coating of EDMP VisPlus 350-700nm on both the front and back surfaces. This coating enhances the lens's transmission properties within the specified wavelength range, further improving its performance in optical systems.
