Sapphire & Ruby Laser Micromachining

Ruby and Sapphire are widely used in precision optics, micro-mechanical devices, and aerospace due to their superior mechanical and optical properties. Our femtosecond laser technology offers a non-contact, high-precision "cold processing" solution specifically designed for these hard, brittle, and transparent materials.

Advantages

✅Zero Heat Damage: The ultra-short pulse creates a Heat Affected Zone (HAZ) of less than 0.2μm. This eliminates heat buildup, preventing discoloration and thermal cracks.

✅Micron-Level Precision: We achieve tolerances of ±1μm. The results are smooth, burr-free, and free of recast layers, requiring no post-polishing.

✅Complex Geometric Forming: We overcome the challenges of transparent materials to etch blind slots, steps, windows, and intricate shapes.

✅High Consistency: Our closed-loop monitoring system ensures that every part in mass production meets strict dimensional standards.

Sapphire Processing

Known for high transparency and chemical stability, Sapphire is the top choice for semiconductor substrates and high-end optics.We solve the focusing issues caused by Sapphire's high transparency.

Ruby Processing

With superior wear resistance and unique color, Ruby is ideal for high-load mechanical parts and precision gear, like 3D printing nozzles, high-pressure water jet nozzles, precision bearings, and custom watch dials.
