Detecting fine surface defects such as scratches and pits on the surface of hard disks.
By irradiating the surface of the hard disk with a high-power laser, we detect fine surface defects such as scratches and pits, classify them by defect type, and display the results. Not only can we detect scratches with high sensitivity through simultaneous irradiation of multiple lasers, but we can also determine the uneven shapes of the defects. Features: - Detection of minute defects using high-power lasers - High scratch detection capability - Discrimination of defect unevenness - Automatic focus for all units - Excellent cost performance - Customization support - Automatic inspection for one cassette - Compatible with transparent glass substrates
