Optical Flaw Detector

The optical flaw detector uses light to illuminate the surface of materials and detects defects such as cracks and bubbles by observing reflected or transmitted images. It is used for surface quality inspection of metals, plastics, and other materials, locating tiny flaws in manufacturing and maintenance processes.
Selection
When selecting, consider detection accuracy and material compatibility, paying attention to the light source type and magnification. Choose the probe specification based on the sample size, as environmental adaptability affects stability. Operational complexity should match personnel skills, and maintenance costs should be factored into long-term usage evaluation.
