Abstract Scope |
Digital fabrication enables precise, flexible, and scalable manufacturing of intricate optical elements from traditional optics to complex microstructures and freeform optics. This paper presents a hybrid approach that combines filament-fed laser additive manufacturing with femtosecond laser micromachining for shaping optical elements with precision. Using a 4-axis CNC stage, substrates are controlled relative to a CO2 laser, locally heated to form optical elements, followed by surface mapping and registration for femtosecond laser micromachining. Machining accuracy and quality through surface roughness and controlled glass reflow to improve quality are also discussed. |
