    Abstract: Provided is a technique capable of more accurately determining a solder protruding defect in an appearance inspection device that acquires an image of an inspection region of an inspection target and measures a height of a predetermined place in the inspection region with a height measurement device. The appearance inspection device includes: an imaging unit (3); a height measurement unit (20); a moving mechanism (5) that moves the imaging unit (3) and the height measurement unit (20). When a restricted region (M) in the inspection target is irradiated with the measurement light emitted from the height measurement unit (20), the determination unit restricts defect determination based on the information on the height of the predetermined place measured by the height measurement unit (20).

    Abstract: An optical metrology device is capable of detection of any combination of photoluminescence light, specular reflection of broadband light, and scattered light from a line across the width of a sample. The metrology device includes a first light source that produces a first illumination line on the sample. A scanning system may be used to scan an illumination spot across the sample to form the illumination line. A detector spectrally images the photoluminescence light emitted along the illumination line. Additionally, a broadband illumination source may be used to produce a second illumination line on the sample, where the detector spectrally images specular reflection of the broadband illumination along the second illumination line. The detector may also image scattered light from the first illumination line. The illumination lines may be scanned across the sample so that all positions on the sample may be measured.

    Abstract: The present invention relates to a device (1) and a method for determining parameters of fluid-containing samples (2) in a system (3) for individually irradiating the samples (2) with light (4) of a light source (5) in an essentially vertical irradiation direction (6). In this case, this system (3) includes a detector (7) for measuring the light (8) coming from a single sample, and this detector (7) has a detection direction (9′), which lies on an optical axis (9) that is essentially parallel to the optical axis (6) of the light source (5). This device (1) includes at least one reflective surface (10), using which the light (4) coming essentially vertically out of the light source (5) may be at least partially deflected in an essentially horizontal irradiation direction (11). The device according to the present invention and the method according to the present invention are distinguished in that the detection direction (9′) of the detector (7)—for measuring the individual light (8) coming from a single sample (2)—is positioned at an angle to the optical axis of the light (4) irradiating the sample (2) in such a way that only the light (8) coming from the individual sample (2), but not this light (4), reaches the detector (7).

    Abstract: A system and method for multimode imaging of at least one sample is disclosed. The system includes at least one light source; an optical system selected responsive to a mode of operation of the imaging system; and a detector capable of selective reading of pixels. The at least one sample is moved elative to the optical system using a sample movement technique selected from the group consisting of step sample moving and continuous sample moving. The method includes the steps of (1) selecting a mode of operation for the imaging system; (2) transmitting light from at least one light source through an optical system selected in response to the mode of operation for the imaging system; (3) moving the at least one sample relative to the optical system using a sample movement technique selected from the group consisting of step sample moving and continuous sample moving; and (4) selectively reading pixels with a detector.
