Quality and Testing

In-House Testing of all Key Specification Elements

Quality and Metrology embedded in Production Lines

Compliance with MIL, ISO and DIN Standards


Quality Control is an integral part of optical components and systems manufacturing at LightPath, or as the saying goes, “If you can’t measure it, you can’t make it”. LightPath has process control methods embedded in our manufacturing operations. Our state-of-the-art metrology equipment on the production floor is used by both the operators and quality inspectors, to measure, control and optimize processes during production runs.
