3.4.6 Lighting Control
The AVR systems include LED-based lighting control. Light is emitted by ultra-bright LEDs mounted directly in the ring light, quad ring light, coaxial light, and collimated sub-stage light. The output of each light source is controlled through and LED controller and the M3 software. The following information provides additional detail the light source options.
Ring Light
Both zoom and telecentric lenses can include a ring light. The ring light illuminates objects from the top with even illumination from all sides. The following figure illustrates the ring light.

Quad Ring Light
The quad ring light enhances the capabilities of the ring light. The quad ring light provides a total of 96 ultra-bright LEDs in four quadrants. Light intensity for each quadrant can be adjusted using the M3 software. The height of the quad ring light is also adjustable. In combination, adjustments of height, direction and light intensity provide very flexible illumination for edge detection. The following figure illustrates the quad ring light.
