Inspection Systems for Glass and Coating Defect Detection

Breaking Technical Barriers

Pursuing High Performance Coupled with Low Cost Systems

For over twenty years, Dark Field Technologies has been leading the glass surface inspection industry with a glass inspection system of new laser and camera inspection and glass coating defect detection technologies, including retro-reflective laser systems for float glass inspection and telecentric lasers and cameras for low-e glass and display glass. There is no maintenance and minimum installation cost, and installation is done during line operation–so no down time.

Your Partner For Complete Inspection & Metrology Solutions, From Product Development Through Production

Contract Inspection

Contract Inspection allows your team to deploy Dark Field’s inspection expertise even in the early days of product and process development.


R&D Tabletop Systems

Turnkey tabletop inspection systems allow pilot lines, Labs and R&D operations to start using SSLR technology early in the product/process development. Systems are modular and may be repurposed to the production line in the future. This means that the Lab or Pilot Line results are directly transferrable to Production.


Solid State Laser Reflection (SSLR) Systems for Pilot Lines and Production

The world’s most advanced technology solution for finding defects and taking measurements in RTR, Sheet and Wafer Production. On-line defect detection to 1µm. Achieve greater throughput, improved quality, minimize scrap, eliminate manual labor, and improve costs – concurrently.


Turnkey Systems

New processes and pilot plants sometimes require a stand-alone, special turnkey system. Dark Field turnkey systems deliver recipe-based defect detection and metrology for all process operations. Systems include XYZ stages and requisite safety interlocks and controls. This system may later be repurposed for Production.


Future Upgrades

As processes and products change or evolve, Dark Field systems may be upgraded for wider and faster operations, greater system resolution and customized software. Dark Field systems are completely modular so they can be upgraded in the field.
