VM11-2 stand-off

RVP stand-off - VM11-2

Stand-off is described as the distance required between the bottom of the vision module and the part feature to ensure optimum metrology performance.

Vision modules have different stand-off distances to allow the inspection of a variety of parts. The stand-off distance for the VM11-2 module is 120 mm.

VM11-2 field of view

RVP field of view - VM11-2

The field of view for each vision module determines the size of feature than can be inspected using a single exposure when the RVP system is at the correct stand-off distance.

The VM11-2 field of view is 12.5 mm × 10 mm; any feature that requires inspection must be within these dimensions to be captured with a single exposure.

RVP module depth of field

The depth of field is the acceptable tolerance range for the focal point of the vision system that will still provide accurate metrology performance.

If the stand-off distance means that the focal point of the vision probe is outside of the 5 mm depth of field tolerance, then a reduction in metrology performance will be apparent.
