Abstract: The sample holder includes support having a thickness and an aperture through the thickness of the support. A tilt mechanism is connected to the support for controlled tilting of the support, and the aperture through the support is configured to have a diameter that increases in a direction through the thickness of the support. This arrangement enables a light beam to pass through the same given area of the sample, irrespective of whether the sample is held perpendicular to the beam or held at a tilted position relative to the beam. In one embodiment, the holder includes an efficient magnetic clamp mechanism for securing the sample to the holder. The holder compactly integrates with tilting mechanisms a sample rotation mechanism.

Abstract: An illuminator for a viewing unit of an optical inspection machine for the quality control of parts, in particular gaskets, comprises a diffusion chamber, a diffuse illumination source, a low-angle illumination source, a direct illumination source placed in the diffusion chamber, and an annular reflective element placed in the diffusion chamber. The annular reflective element is integral to the direct illumination source so that together they form a chamber closure assembly delimiting the upper end of the diffusion chamber. The chamber closure assembly can move axially by translational movement in the diffusion chamber both toward and away from the diffuse illumination source.

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.

Abstract: An inspection system is configured for use with a conveyer apparatus including carrier bars. Each carrier bar conveys pellet-shaped articles along a predetermined path. The inspection system includes at least one camera unit for sensing a predetermined characteristic of the pellet-shaped articles, a removal unit, and a controller. The removal unit, downstream from the at least one camera unit, removes selected pellet-shaped article(s) from the carrier bar(s) depending on whether the characteristic is sensed by the at least one camera unit. The controller is in communication with the at least one camera unit and the removal unit. The controller provides a signal to the removal unit in accordance with the sensed characteristic. The removal unit includes a rotatable ejection drum having extended vacuum nozzles along its length, equal to the number of articles conveyed in each carrier bar. Each vacuum nozzle selectively removes article(s) from the carrier bar(s) by suction.

Abstract: A multi-color fluorescent excitation and detection device comprises at least one illumination module, a cartridge and at least one detection module. The illumination module provides an illumination light at specified range of wavelengths. The cartridge comprises a detection chip comprising plural detection wells arranged around the peripheral of the detection chip. The detection chip is circular shape. Each of the detection wells is accommodated a corresponding fluorescent dye therein. Each of the detection wells includes a first wall and a second wall. The illumination light transmits through the first wall to illuminate on the fluorescent sample so as to excite a fluorescent signal, and the fluorescent signal generated from the fluorescent sample transmits through the second wall. The detection module receives the fluorescent signal and convert the fluorescent signal to an electrical signal.
