  • Publication number: 20240125592
    Abstract: The present disclosure relates to a beam measuring device, a sample processor including the beam measuring device, and a method of measuring a beam using the beam measuring device. The beam measuring device includes a detection unit and a light impediment unit. The light impediment unit is located between the detection unit and a light source, and is configured to generate a shadow area on the detection unit by blocking transmission of part of a beam coming from the light source. The detection unit is configured to measure the shadow area, and to determine whether the beam is divergent or inclined with respect to a predetermined optical axis based on the measurement of the shadow area. The beam measuring device may shorten the optical detection channel and ensure the detection accuracy, thereby having a compact structure. In addition, the beam measuring device may measure divergence angle and directionality, respectively.
