  • Patent number: 10989660
    Abstract: An automatic fluorescence detection system includes a base and an optical assembly. The base has a detecting region. The optical assembly includes a fluorescent image-capturing device, an illumination device and a field lens. The illumination device includes a first annular illumination module and a second annular illumination module surrounding a center axis of the fluorescent image-capturing device. Lights emitted by the first annular illumination module and the second annular illumination module travel along a light-traveling path to project onto the detecting region. A distance between the first annular illumination module and the center axis is smaller than that between the second annular illumination module and the center axis. The field lens is disposed in correspondence with the detecting region. Spacing between the field lens and the detecting region is ranged from 15.0 cm to 30.0 cm.

  • Patent number: 10411646
    Abstract: A method for inspecting a solar cell and configured to inspect a peeling state of a three-dimensional pattern of the solar cell includes obliquely illuminating the three-dimensional pattern of the solar cell using a light beam. An image of the solar cell is normally captured. An intensity of the light beam is increased to increase a contrast between the three-dimensional pattern and a shadow of the three-dimensional pattern in the image and increase a contrast between an ink pattern of the solar cell and the shadow in the image to overexpose the ink pattern in the image. Determine if the three-dimensional pattern is peeling according to the shadow of the three-dimensional pattern in the image.

  • Publication number: 20120182549
    Abstract: The present invention discloses a light source with uniform chromaticity and luminance and a color sensor having the same. The light source includes multiple LED devices, a primary light guide plate assembly and a secondary light guide plate assembly. The chromaticity and luminance of light emitted from the LED devices are uniformized for the first time in the primary light guide plate assembly and then guided into the secondary light guide plate assembly for the secondary chromaticity and luminance uniformization, to thereby act as the light source of the color sensor. Therefore, the light source not only provides better chromaticity and luminance uniformization effects, but is further qualified as the standard illuminant D65, thereby enabling more precise color sensor inspection results.
