optoNCDT Laser Triangulation Sensors


Precise distance measurements on rough and structured surfaces

Rough and structured surfaces cause interferences within the laser point (left) which leads to a faulty projection on the sensor element. This effect becomes particularly obvious with metallic surfaces. The small laser line of the optoNCDT LL sensors compensates for this effect (right) and enables stable measurements on metallic surfaces.


Precise and stable measurements on metallic surfaces

Laser-line sensors for reliable measurements on metallic surfaces

The optoNCDT LL sensors operate with a small laser line. The laser line and special software algorithms compensate for disturbances caused by surface roughness, defects, indentations or minute holes on metallic surfaces. This is how optoNCDT LL sensors achieve the highest precision with measurement tasks involving metals.


Precise distance measurements on reflecting surfaces

Requires special sensor alignment for reflecting surfaces:
angle of incidence = angle of reflection




Specially aligned DR sensors from Micro-Epsilon provide high accuracy and signal stability on directly reflecting surfaces







Multiple measuring ranges for versatile measurement tasks

  •  >85 sensor variants with measuring ranges from 2 - 1000 mm
  •  Covers a larger number of applications in many industries



Long-range sensors for measurements from a safe distance

  •  Long-range sensors: Large measuring range & offset distance
  •  Measurements with high accuracy from a safe distance



Unique ease of use

  •  Intuitive operation via web interface
  •  Diverse options for processing values and signals, e.g., filters, peak selection



The quality slider enables the user to define the signal evaluation regarding process and measurement dynamics. Depending on the selected settings, the measuring rate and the averaging of the sensor are adapted.    

Wiith the pre-sets, predefined sensor settings for specific measuring objects can be quickly and easily adopted.


e.g., metal, ceramics,...

e.g., circuit boards, PCB,...

e.g., milk glass, plastics,....

Certified precision

Calibration certificate of all supplied sensors confirms the achieved performance









High precision with changing surfaces

optoNCDT sensors are equipped with intelligent control features which ensure high signal stability with bright/dark transition, regardless of the color and the brightness of the measuring object. This optimally adjusts the exposure time or the amount of light for the exposure cycle just performed or the next exposure cycle. These controls enable smooth signal courses without outliers even in dynamic measurements.



Stable control regardless of color & brightness

  •  Real-Time-Surface-Compensation
  •  Measuring the degree of reflection during exposure and control in real-time

The Active Surface Compensation provides stable distance signal control regardless of target color or brightness.


The Advanced Surface Compensation feature operates with new algorithms and enables stable measurement results even on demanding surfaces.


The real time surface compensation feature compensates for changing reflectance properties in the current measurement cycle. Each individual laser pulse is controlled in real time depending on the surface properties of the measuring object.


The Advanced Real Time Surface Compensation with its improved dynamic range enables a more precise real time surface compensation. This ensures maximum compensation of fluctuating reflectivity while generating stable measurement values with high accuracy.
