67-281 50mm Dia. UVFS Aspheric Lens; EFL=40mm; NA=0.63 NIR 600-1050nm

This is the 67-281 model from Edmund Optics, a 50mm diameter UVFS (Ultra-Violet Fused Silica) Aspheric Lens, designed with an effective focal length of 40mm and a numerical aperture of 0.63, specifically coated for the Near-Infrared spectrum of 600-1050nm.

The lens is made of high-quality syn hpfs7980 corning material, ensuring durability and excellent optical performance. Its aspheric design allows for superior image quality, minimizing spherical aberration and distortion often associated with traditional spherical lenses. The lens has a large numerical aperture, enabling high light-gathering capabilities and excellent resolution.

The geometry of the lens includes an inner radius of 0mm, an outer radius of 0mm, a diameter of 50mm, a thickness at the edge of 4.07mm, and a center thickness of 27.5mm. The front and back surfaces are coated with Edmund Optics' NIR coating, specifically designed for the 600-1050nm range, enhancing transmission and protecting the lens from environmental factors.

This lens is ideal for applications that require high-resolution imaging, wide fields of view, and efficient light transmission in the Near-Infrared spectrum, such as biomedical imaging, machine vision, and scientific research.
