Introduction to Aspheric Lenses:

The aspheric glass lens is formed by pressing the ball with a precision mold after softening it at high temperature. A single-element design helps reduce the number of lenses in a multi-lens optical assembly. In other words, unlike conventional lenses with spherical shape, aspheric lenses have a more complex surface that continuously changes in curvature l gradually from the center of the lens to the edge of the lens. Therefore, in addition to the inherent good refractive index, dispersion characteristics and environmental adaptability of glass lenses, aspheric glass lenses can better correct distortion and equiaxial aberrations, thereby reducing the number of optical components used and simplifying the system structure. Improve the imaging quality of the optical system.

Advantages:

The advantages of aspheric lens are: improving the imaging quality of the system, simplifying the complexity of the structure, and improving the reliability of the system.

One of the most significant advantages is the correction of spherical aberration caused by spherical lenses in collimating and focusing systems. By adjusting the surface constant and aspheric coefficient, the aspheric lens can eliminate the spherical aberration to the greatest extent. Aspheric lenses (light converging to the same point, providing optical quality) essentially eliminates the spherical aberration (light converging to different points, resulting in blurry images) produced by spherical lenses. Incorporating aspheric surfaces into applications such as focusing the output of a laser diode can not only reduce overall cost, but can also outperform components designed using traditional spherical optical lenses.
