850 Color Video System A motorized zoom lens allows the operator to optimize viewing with its standard range of 10x to 100x. Other ranges are available. The system has two separate fiber optic ring light illuminators with separate controls for each, one illuminating the die and the other illuminating the substrate. A micrometer stage is used to adjust X, Y, and Theta to move the substrate into exact alignment with the die. Table movement is controlled by a joystick.
Pneumatic brakes lock the table in position.

This unit may be purchased as a field upgrade. The heated stage is capable of 250 C operation. It incorporates a separate control box with its own closed loop temperature controls.
