49-593 25mm Dia. UVFS Aspheric Lens; EFL=25mm; NA=0.5 NIR 600-1050nm

This is a 25mm diameter aspheric lens, catalog number 49-593, offered by Edmund Optics. The lens is made of UV fused silica, specifically Corning's syn hpfs7980, and features a 0.5 numerical aperture (NA). The lens is designed for use in the near-infrared (NIR) spectrum, specifically between 600 and 1050 nanometers.

The lens has an effective focal length (EFL) of 25mm and a thickness of 1.75mm at the edge, reducing to 9.75mm at the center. The front and back surfaces of the lens are coated with Edmund Optics' NIR coating for improved performance in the 600-1050nm range.

The aspheric design of the lens, with a first radius of curvature (R1) of 11.462mm and a conic constant (K1) of -1.661222, helps to minimize spherical aberration and other optical aberrations, providing superior image quality. The lens is suitable for a wide range of applications, including imaging, beam shaping, and laser applications in the NIR spectrum.
