Dynamic scanning optical system optics:1pc small focus lens、1-2pcs focus lens、Galvo mirror.The entire optical lens forms a function of beam expansion, focusing and beam deflection and scanning.
The expanding part is a negative lens, ie small focus lens, which realizes beam expansion and moving zoom, the focusing lens is composed of a group of positive lenses. The galvo mirror is mirror in the galvanometer system.
(1) Optimization of lens design: Optimum ratio of diameter to thickness ratio
(2) Lens high damage threshold:>30J/cm2 10ns
(3) Ultra-low absorption coating, absorption rate:<20ppm
(4) Galvanometer thickness to diameter ratio: 1：35
(5) Lens surface accuracy:<= λ/5
