  • Patent number: 12110480
    Abstract: An observation device includes a microscope. The microscope includes an illumination light beam source, an illumination optical system, and an observation optical system forming an optical image of an observation target from reflected light beams obtained by reflection of illumination light beams by the observation target. The observation optical system includes a phase plate changing the phase of directly reflected light beams reflected on a reflection surface among the reflected light beams. Both the illumination optical system and the observation optical system are arranged under the observation target. The observation device includes an image pickup device photoelectrically converting the optical image obtained by the observation optical system to create image data of the observation target and a display device displaying the image data.

  • Patent number: 11971363
    Abstract: A foreign matter inspection system that is less likely to misidentify a crack as a foreign matter during an image inspection in which a vibration is applied to a powder contained in a bag-like container. The foreign matter inspection system includes a vibration device configured to apply a vibration to a container, a photography device configured to optically photograph the inside of the container through a transparent area, and a determination device configured to determine whether a foreign matter is present inside the container based on an image of the container photographed by the photography device. The vibration device alternately applies weak vibrations W and strong vibrations S to the container. The determination device determines whether the foreign matter is present inside the container based on the image of the container photographed by the photography device when the vibration device applies the weak vibrations W.
