22-758 15mm Dia. N-SF6 Precision Aspheric Lens; EFL=9mm; NA=0.83 NIR-Plus 600-1050nm

This is the 22-758 model from Edmund Optics, a high-precision aspheric lens with a 15mm diameter and a numerical aperture (NA) of 0.83. The lens is designed for use in the near-infrared spectrum, specifically between 600 and 1050nm.

The lens is made from N-SF6 Schott, a high-refractive index glass that is often used in optical systems requiring high performance. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional spherical lenses, resulting in improved image quality.

The lens has an effective focal length (EFL) of 9mm, which is the distance from the lens's optical center to the point at which light rays converge. This makes the lens suitable for use in compact optical systems where space is at a premium.

The lens also features a precision-ground edge with a thickness of 5.28mm, providing robustness and durability. The center thickness of the lens is 9.7mm, which can be important for certain optical system designs.

The lens is coated with Edmund Optics' NIR-Plus 600-1050nm coating on both the front and back surfaces. This coating is designed to enhance the lens's performance in the near-infrared spectrum, reducing reflection and increasing transmission.

The lens is currently in stock and available for purchase through the Edmund Optics website.
