1. Overview

Optical inspection equipment accessories are modular components that enhance the functionality, precision, and adaptability of optical inspection systems. These accessories include illumination sources, lenses, sensors, filters, and software modules. They play a critical role in industrial quality control, semiconductor manufacturing, biomedical imaging, and precision measurement by enabling accurate defect detection, dimensional analysis, and material characterization.
