Precision Laser Micromachining for Optics & Photonics
Enabling the next generation of optical innovation with micron precision. From micro-lenses and diffraction gratings to photonic waveguides and AR combiners, we transform your optical designs into reality with nanosecond laser technology.
Photonics Manufacturing Challenges We Solve
Precision laser micromachining solutions tailored for the unique demands of optical component manufacturing
Micron Feature Precision
Optical components require features at the micron scale—diffraction gratings with line densities exceeding 1000 lines/mm, micro-lens arrays with profiles accurate to nanometers, and waveguide structures where deviations compromise optical performance.
Our Solution
Advanced fiber laser systems with 10μm positioning resolution and active beam stabilization, achieving ±5μm feature accuracy on complex optical geometries. Optimized for metals, thin films, and select non-metal substrates used in photonics assembly.
Zero Thermal Impact
Traditional laser processing creates heat-affected zones thatcause refractive index changes, stress birefringence, andmicro-cracks-destroying optical performance in precisioncomponents.
Our Solution
Precision pulse control with ultrafast picosecond/nanosecond fiber laser platforms—minimized heat transfer, tightly confined HAZ, and edge quality suitable for optical mounting fixtures, metal apertures, and reflective components where thermal damage must be controlled.
Complex 3D Metal Micro-Structures
Modern photonics and precision instrumentation demand increasingly complex metal structures—angled apertures for optical benches, multi-layer stacked shields, folded flexure mounts, and 3D micro-assemblies where conventional stamping or etching cannot achieve required precision or edge quality.
Our Solution
Multi-axis laser processing with precision motion control, enabling 3D micromachining of metal components including beveled edges, angled cuts, and welded multi-layer assemblies for optical and MEMS applications.
