16-275 45mm Dia. S-LAH64 NIR Aspheric Lens; EFL=32mm; NA=0.7 VIS Plus 350-700nm

The 16-275 is a high-performance aspheric lens, designed and manufactured by Edmund Optics. This lens boasts a 45mm diameter and a numerical aperture (NA) of 0.7, making it suitable for a wide range of applications. The lens is made from S-LAH64, a high-quality optical glass from Ohara, ensuring excellent optical performance.

The lens is designed to work within the visible (VIS) and near-infrared (NIR) spectrum, specifically between 350 and 700nm. This makes it a versatile choice for applications that require high-resolution imaging or light collection within this spectrum. The lens has an effective focal length (EFL) of 32mm, which, combined with its NA, provides a wide field of view and high light-gathering capability.

The lens features a precision-ground aspheric surface on one side, which helps to correct spherical aberration and distortion, common issues in optical systems. This results in improved image quality, with sharper, clearer images. The other side of the lens is planar, providing a flat surface for coupling with other optical elements.

The lens is coated with Edmund Optics' VIS Plus coating, which is designed for the 350-700nm spectrum. This coating reduces surface reflections, improving transmission and reducing ghosting and flare. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance in both transmission and reflection.
