Abstract:
An electronic component inspection equipment for optically inspecting an external shape of an electronic component accommodated in a vessel, comprising:illumination means for irradiating illumination light to the electronic component; image pick-up means which determines as image pick-up directions both a first direction satisfying a Brewster angle to a first side wall of the vessel and a second direction satisfying the Brewster angle to a second side wall having an angle with respect to the first side wall; first selection means which is disposed on the first direction to preferentially select P polarized light wave to the first side wall and leads the selected P polarized light wave to the image pick-up means; and second selection means which is disposed on the second direction to preferentially select P polarized light wave to the second side wall and leads the selected P polarized light wave to the image pick-up means.
