          *1 Classification performed based on IEC60825-1 in accordance with FDA (CDRH) Laser Notice No. 56.
          *2 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.
          *3 Values measured by averaging 4096 times at the reference distance.
          *4 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.
          *5 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.
          *6 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.
          *7 A characteristic that allows for stable, high-accuracy measurement with a single capture (exposure) at all levels of reflectance,from black (low) to glossy surfaces (high).
          *8 The value when a head cable (CB-B*) or extension cable (CB-B*E) is connected.
          *9 When measuring white paper, illuminance on the sensor head receiving surface when light is applied to white paper.
          *10 The head needs to be mounted to a metal plate to be used.
