Abstract

This application relates to a dark field illumination device for assisting machine vision in providing illumination during object inspection. It includes a base and a three-axis motion module mounted on the base. The three-axis motion module consists of manual lead screws that adjust the emission position of the light source in the X, Y, and Z directions. It connects to a pitch base and a pitch movable seat of a double-sided clamp. The double-sided clamps hold the light source, and the pitch movable seat adjusts the emission angle of the light source. This dark field illumination device can accommodate different types of light sources, precisely adjust the emission position and angle of the light source, and is simple to operate.
