The Multi-Modal Defect Inspection Instrument For Large-Aperture Optics (MMDI-2000-LA) integrates full-aperture rapid defect identification with sub-aperture high-sensitivity, high-resolution microscopic imaging. It employs laser scattering for full-aperture rapid scanning and imaging of large-aperture optical components, enabling statistical analysis of defect size, location, and morphology. The system combines multiple inspection modalities—including photothermal weak absorption, bright-field microscopy, dark-field microscopy, and laser confocal microscopy—to focus on user-specified defect regions and extract detailed defect information.
