The aspheric lens has a better curvature radius and can maintain good aberration correction to obtain the required performance. The application of the aspheric lens brings excellent sharpness and higher resolution.
Generally speaking, compared with germanium lenses, Infrared Aspheric Lenses are more popular in the high-precision optics and infrared imaging industries.
