From single lenses to multi-lens groups, from spherical to aspherical surfaces, from simple coatings to multi-layer optical films, aberration correction technology for convex lenses has been continuously evolving.
The mathematical relationships in convex lens imaging are not only the foundation of optical theory, but also the support for the development of modern optical technology.
In the precise order of the optical world, the path of light is not always a straight line.
In modern optical systems, convex lenses—as one of the most fundamental and widely used optical spherical lenses—continue to play an irreplaceable role in numerous high-precision fields such as scientific research, industry, medicine, and communications,
Taking a single-layer antireflective film as an example, its thickness needs to be accurate to the nanometer level to ensure that the optical path difference between the two reflected beams is an odd multiple of half the wavelength.
In cylinder lens processing, surface roughness is a key quality indicator and plays a decisive role in controlling beam quality.
