Optical Inspection

Definition

Optical inspection is a non-destructive testing technique that uses light-based methods to evaluate the quality and integrity of materials or components. This approach often employs cameras and optical sensors to detect defects, measure dimensions, and analyze surface characteristics, making it essential for maintaining product quality during manufacturing processes. By integrating optical inspection into production, manufacturers can optimize their processes, reduce waste, and ensure compliance with quality standards.
