Micro Aspheric Convex Lenses Fabricated by Precise Scraping
An easy, fast, inexpensive, and simple method utilizing a microshaper with a very small knife nose is used to fabricate microconvex aspherical lenses.The microshaper is mounted on a computer numerical control (CNC) machine.To achieve an accurately designed profile of the lens surface, a cutter-path planning algorithm with compensation for knife int
