3.1.4 Illumination modes 
The TM-500 series supports the following illumination modes. Select appropriate illumination mode
according to your application.
(1) Contour illumination
The contour illumination generates the contour image of a workpiece, and is suited for measurement
and inspection of workpiece contours. The illuminator is equipped with a green filter.
(2) Surface illumination 
Surface illumination shows the surface of a workpiece, and is used in observation and inspection of
workpiece surfaces. Adjust the angle and orientation of this illuminator so the workpiece surface can
be observed under optimum conditions.
(3) Simultaneous use of contour and surface illuminations 
Both the contour and surface of a workpiece can be observed simultaneously.
