Precision laser welding provides that critical bridge between a glass-to-metal sealed component and a fully hermetic optical assembly. Laser-welding of optical elements requires expertise in precise metal-to-metal seals as well as an understanding of the care and handling required for optical materials, surfaces, and coatings — it becomes a literal fusion of tooling and process to provide a successful outcome.
Access Optics has manufactured tens of thousands of laser-welded hermetic optical assemblies, each one the product of painstaking qualification and process validation to ensure:
- control of weld depth
- freedom from cracking and embrittlement
- control of stress conditions in the optics [which prevents downstream failure due to cracking or chipping]
