Selecting a Measurement Sensor

Thickness / Width

Although systems with two sensors are common, if the position of one side is predetermined or if the target is transparent, measurement with one sensor is possible.
Detection methods differ according to the measurement conditions, and sometimes special arrangements can be made. Contact your nearest sales office with any questions.

Triangulation Reflection Method
LK Series
LK Series

Thickness measurements are performed using two sensors to sandwich the target. With a transparent target, the thickness can be directly measured through exposure from only one side.

Point of selection

  • Target selection not determined by transparency/opacity or colour
  • 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 / LS Series
TM Series / LS Series

Thickness measurement is performed by measuring the height of a target as a step height relative to a reference surface.

Point of selection

  • Measurement possible at multiple locations simultaneously
  • Highly stable
LS-9000 Series
High-Speed Optical Micrometer
LS-9000 Series
Contact-Type
GT Series
GT Series

Thickness measurements are performed using two sensors to sandwich the target. The contact-type system allows for highly accurate measurement.

Point of selection

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