Dome light illumination techniques
A dome light radiates indirect light at various angles due to the LEDs being mounted facing up and shining into the dome. When standard lighting is used, direct reflection from the part can result in a hotspot (halation), causing inspection and reliability problems. As the dome light diffuses at all angles, a target with a complicated shape can be uniformly lit, eliminating hot spots and increasing inspection stability.
