The progress of science and technology has directly affected the development of lens optics, and the requirements for high-performance optics have been a driving force behind improvement in this field. I will introduce various improvements in lens optics in which I have had a hand, and which make me firmly believe that the development of lens optics will never cease, thus leading us to conclude that “Lens optics will be brilliant forever”.

Key words: lens optics, aberration, object distance, aspherical surface, fine undulation, waviness, lithography, local flare, imaging theory, incoming inclination factor
