Measurable quality – prove what we promise
At General Optics, precision metrology and verification form the foundation of our commitment to delivering optical components that meet and exceed customer specifications. Every optic is measured, validated, and certified using state-of-the-art equipment and internationally recognized standards. Our inspection processes ensure full compliance with MIL-SPEC requirements.
Precision Fabrication Verification
Advanced measurement systems validate that every optic we fabricate truly meets its designed form, ensuring a level of accuracy that machining alone cannot guarantee.
- Zygo Interferometer (4″, 15″)
Surface form and irregularity inspection for flat, spherical, DOE, and freeform optics - TalySurf PGI Optics
High-precision surface profiling for aspheric, DOE, and freeform optics - Coordinate Measuring Machine (CMM)
Dimensional verification for optical components up to Ø 1850 mm - Autocollimator & Alignment Telescope
Wedge angle, centering, and optical alignment error inspection - Tool Microscope
Surface defect and scratch-dig inspection in accordance with ISO / MIL standards
