16-964 30mm Dia. N-SF5 Precision Aspheric Lens; EFL=22.5mm; NA=0.66 VIS-EXT Plus 350-700nm
The 16-964 is a high-precision aspheric lens offered by Edmund Optics, designed for use within the visible light spectrum, specifically between 350-700nm. This lens is constructed from N-SF5 Schott, a high-refractive index glass, and features a 30mm diameter and a numerical aperture (NA) of 0.66.
The lens boasts an effective focal length (EFL) of 22.5mm, making it suitable for a variety of 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, thereby improving the overall image quality.
The lens is coated with Edmund Optics' VIS-EXT Plus coating, which is specifically designed for the 350-700nm range. This coating enhances the lens's transmission capabilities, reduces surface reflections, and increases the overall durability of the lens.
The geometry of the lens includes an inner radius of 0mm, an outer radius of 0mm, a thickness at the edge of 6.62mm, and a thickness at the center of 15mm. The front and back surfaces of the lens are coated with the same VIS-EXT Plus coating, ensuring consistent performance across the entire lens.
