Precision optical flat glass is a fused quartz optical component that can be used as a reference to determine the flatness of unknown surfaces. For jobs with low requirements, we provide flatness made of BK7 specified as λ/ 4 or better. These optical planes can also be used as windows.
Precision optical flat glass undergoes high-precision grinding and polishing, resulting in good surface flatness. It is a preferred choice for interferometry, imaging systems, laser applications, and automatic calibration.
