          *1 When range is extended.
          *2 Classification performed based on IEC60825-1 in accordance with FDA (CDRH) Laser Notice No. 56.
          *3 Do not view the beam directly using optical instruments (such as eye loupes, magnifiers, microscopes, telescopes, or binoculars).
          Observing the laser output using optical instruments is dangerous and may damage the eyes.
          *4 Values measured by averaging 4096 times at the reference distance.
          *5 The measured target is a KEYENCE standard target. Value when the average height of the default setting area is measured with height and position tools. All other settings are default values.
          *6 The measured target is a pin gauge. Value when the point of intersection for the pin gauge rounded surface and edge level is measured using height and position tools. All other settings are default values.
          *7 The measured target is a KEYENCE standard target. Profile data when measured by smoothing 64 times and averaging 8 times. All other settings are default values. Values inside parentheses are representative examples of averages for all profile data.
          *8 Profile data interval can be selected. If it is modified, the X-axis measuring range will also change.
          *9 Values inside parentheses cannot be used when connecting with LJ-X8000A.
          *10 A characteristic that allows for stable, high-precision measurement with a single capture (exposure) at all levels of reflectance,
          from black (low) to glossy surfaces (high).
          *11 The value when a head cable (CB-B*) or extension cable (CB-B*E) is connected. Does not include CB-B**L connection.
          *12 When measuring white paper, illuminance on the sensor head receiving surface when light is applied to white paper.
          *13 The head needs to be mounted to a metal plate to be used.
