Owens Design’s phased approach to factory equipment development starts with modular architecture definition, followed by high risk module proof-of-concept, culminating in a fully automated production line. In one example, the completed line consisted of over 36 process stations, 24 robots, 29 inspection & alignment cameras, and 19 computers.

• Precision optical assembly and alignment
  • Alignment tolerances less than 25 µm.
  • Pressure sensitive adhesive application while preventing air gaps
• Machine vision - pre and post inspection
