Lithography lens very different than camera lens. They are huge lens.
Lithography equipment also use huge mirrors.
Lens maker with very strong expertise can make lens for lithography such as Carl Zeiss and Nikon.
This area China is very weak.
What are you talking BS? AMEC make 14 nm Lithograph So they should have domestic source of lens otherwise what is the use of domestic lithograph if they don't have local source
