Plano-convex Spherical Lenses versus Aspheric Lenses. In terms of imaging quality, aspheric clearly dominates, but the differences between aspheric lenses and Plano-convex Spherical Lenses are still reflected in higher production/measurement requirements and higher process costs. The table below shows a basic comparison of the two lenses.

The combination of the two lens types can achieve very good imaging. In the difference between aspheric lenses and Plano-convex Spherical Lenses, since spherical lenses usually have lower cost, the number of aspheric lenses in the optical system is usually reduced while ensuring better imaging effects.
The importance of deciding which lens type to use depends on the respective application and optical requirements for image quality, such as improving spherical aberration or achromatic aspects of Plano-convex Spherical Lenses. From an aspheric lens manufacturing perspective, as production processes continue to evolve, the focus will increasingly turn to the impact of lens surface quality rather than cost. Because as the quality of the lens surface improves, many optical tasks can be solved more and more efficiently.
The requirements for new technologies based on high-quality optics will continue to increase requiring more complex and powerful optics, Plano-convex Spherical Lenses will increasingly turn to optical surface quality, which will have a positive effect on customer-specific requirements impact, as many optical tasks can be solved more and more efficiently as the surface quality of optical components improves. Spherical and aspheric optical systems will continue to play a decisive role in the cost-effective realization of new applications based on photonic solutions.
Through the above introduction and analysis of Choose Plano-convex Spherical Lenses or Aspherical Lenses, hope it helps you.
