Best-Fit Applications
Where Gemini Fits Best
Gemini is selected when a bridge CMM still fits the part envelope but the tolerance target, scanning workflow, or repeatability requirement calls for a higher accuracy class.
Precision components
Use Gemini when tighter bridge CMM accuracy and scanning-oriented workflows are important.
Aerospace components
A strong fit for aerospace components that need stable bridge CMM accuracy, scanning workflows, and repeatable controlled-room inspection.
consumer electronics / precision components
Good when the part fits a bridge CMM but the application needs a higher accuracy class than Polaris.
