Aspheric lenses possess varying radii of curvature across their surfaces, enabling them to eliminate spherical aberration and other optical errors that are uncorrectable by conventional spherical lenses. The application of aspheric lenses results in improved light collection accuracy and enhanced imaging quality for the entire optical system. Aspheric lenses are also advantageous in reducing weight, volume, and cost, as they can replace multi-lens systems. These lenses find significant usage in various fields such as night imaging, instrument flaw detection, infrared thermal imaging, infrared temperature measurement, infrared distance measurement, and other related applications.
