Selecting a Measurement Sensor

Height / Step Height

Height is measured by detecting the position of an object's top surface. For objects with bottom surfaces that are not fixed, shapes are directly measured by using two sensors or by projecting the laser in a horizontal line.

Light-Cut Method
LJ Series
LJ Series

The position of an object's top surface is detected.
The ability to perform non-contact 2D profile measurements makes it possible to perform step measurement with respect to a reference plane on the target.

Point of selection

  • Possible to measure 2D height within a line
  • Unlimited target selection at ultra-high speeds
  • Ability to output waveform data
LJ-V Series
Ultra-High Speed In-line Profilometer
LJ-V Series
Triangulation Reflection Method
LK Series
LK Series

The position of an object's top surface is detected.
Non-contact sampling is performed at high speeds, so stable measurement is possible even if the target moves.

Point of selection

  • Target selection not determined by transparency/opacity or color
  • Non-contact measurement possible
  • Small beam spot and high speed
LK-G5000 Series
Ultra High-Speed/High-Accuracy Laser Displacement Sensor
LK-G5000 Series
Optical Thrubeam Method
TM Series
TM Series

By capturing the shadow of a target's shape, the sensor can detect any position. Simultaneous measurement of multiple points is also possible.

Point of selection

  • Measurement possible at multiple points simultaneously
  • Highly stable
TM-3000 Series
High-Speed 2D Measurement Sensor
TM-3000 Series
Contact-Type
GT Series
GT Series

The position of an object's top surface is detected.
The contact-type system allows for highly accurate measurement.

Point of selection

  • Target selection only determined by solidity
  • High-precision measurement possible
