Panasonic LightPix AE20 User Manual page 23

Installation distance between the main unit and the inspection object
Keep 15 to 220 mm space between the object and the main unit, but the space varies depending on the
product number of the main unit. Since light guides (two red LED lights) are emitted from the LightPixAE20
to the area around the object, adjust the position of the main unit so that the two lights are close (or overlap)
each other.
Proper
Installation angle
If you want to capture a shiny object, the light emitted from white LED may interfere with the object due to
the mirror reflection from it, so slant the main unit.
•
Disturbance light, of which illumination intensity varies at the time of measurement, negatively
affects the measurement results. Shield the device from any disturbance light.
•
The larger the installation angle, the greater the warp generated in the captured mages. This will
lead to mixed measurement results depending on the position of the object within the field of
view. Determine the installation angle of the main unit after actually checking the image.
