Abstract:
1. An apparatus for inspection of an electronic component disposed in a measurement plane, comprising: at least one light source provided for generating substantially homogeneous light and illuminating said measurement plane; a camera; a first light path between said camera and said measurement plane, said first light path having a first section between said measurement plane and a first optical element and a second section between said first optical element and a second optical element, said first section of said first light path being substantially perpendicular to said measurement plane; and a second light path between said camera and said measurement plane, said second light path having a first section between said measurement plane and a third optical element and a second section between said third optical element and a fourth optical element wherein said at least one light source comprises first and second light sources to produce light in non-overlapping wavelength ranges.
