^1Imaging mode: Multi emission (optimizing light), Multi emission (synthesis) are not available. ^2LJ-V7000(P), LJ-V7001(P) cannot be connected. They are used with Vision controller. ^3The double polarization function cannot be used. ^4Do not look into the beam directly using any optical instruments (such as eye loupes, magnifiers, microscopes, telescopes, or binoculars). Viewing the laser output with an optical instrument may pose an eye hazard. ^5The laser classification for FDA(CDRH) is implemented based on IEC60825-1 in accordance with the requirements of Laser Notice No. 50. ^6This value is from a case in which measurement has been performed with a reference distance with 4,096 times of averaging. ^7The measurement targets are KEYENCE standard targets. This value is from a case in which the average height of the default setting area has been measured in height mode. All other settings are default. ^8The measurement target is a pin gauge. This value is from a case in which the position of the intersection between the rounded surface of the pin gauge and the edge level has been measured in position mode. All other settings are default. ^9The measurement targets are KEYENCE standard targets. The profile data is from a case in which measurement has been performed with 64 times of smoothing and 8 times of averaging. All other settings are default. ^10Sampling frequency depends on the setting of measurement range, binning and parallel imaging. ^11This value is from a case in which the sensor head cable (CB-B) or extension cable (CB-BE) has been connected. ^{ 12}This is the illuminance for the light-receiving surface of the sensor head during white paper measurement when light has been shined onto the white paper. ^{* 13}The sensor head must be mounted on a metal plate for use.
