LS Series

These sensors can be used on any manufacturing line to perform the shape measurements required for quality management of parts and materials. With the FASTUS LS series, high-accuracy 2D measurement sensor achieved both super cost effectiveness and significantly high speed measurement that conventional 1D measurement sensors can't achieve.
These are next generation 2D displacement sensors that have created a whole new category in part measurement.

• High speed, compact size and low price are achieved using Optex-FA original method

  Employing a mathematical operation known as a projection transformation, which converts a captured image into distance, allows both height and width to be measured with a high degree of precision. Also, by employing Optex-FA original method in which projection transformations, normally performed on all pixels in the case of competitors’ products, are performed after triangulation, processing levels are significantly compressed, allowing high speed to be achieved. Furthermore, a more compact and low cost product has been realized by making processors smaller size.

• 

The LS series can be configured in four easy steps: camera imaging, area measurement and area calculation, and result judgment and output.

Measurement result and “Profile + Measurement result” can be stored and those data can be sent to PC through RS-485 communication. All the sampling data can be obtained regardless of the communication speed, and by using the LS-Navigator, it is possible to obtain data without the use of programs.
Because obtained data can be saved in CSV format, it can be accessed using spreadsheet software, etc.

Various measurement functions

• Height

  

  Average, peak, and bottom heights can be measured.
  Average values, max. values, and min. values of a profile within an area are output.

• Position

  

  Peak, bottom, and edge positions can be measured.

• Width

  

  Groove and height difference widths can be measured. Profile widths are detected using the center position in the height direction of the area.

• Edge count

  

  The number of times the center of the area's height is crossed is counted.
  Use is also possible for pin counts, etc.

• Tilt (°)

  

  A straight line approximating the profile is created and its tilt is measured. (Unit: °) The angles of both sides of grooves and protrusions are measured and calculated.

• Area (mm²)

  

  The area between an area and a profile is calculated
  Measuring the “↑” portion reveals the cross-section of the protrusion, while the “↓” portion reveals the cross-section of the concave.

• Line length

  

  The profile length is measured. Because the same value will be achieved even if the position is changed, usage is possible without having to perform position corrections.

• Diameter

  

  The diameter of the approximate bending line of the measured results is measured. This can be used for calculating the diameters cylinders, protrusions or grooves.

A wide-range of measurement variations using area calculations

• ▪ Example of height difference measurement

  

  Height is measured at two areas (top and bottom surfaces) from which the height difference can be measured by subtracting. Small unevenness and variations can be ignored and it is possible to perform more stable measurements than with 1D displacement sensors.

• ▪ Example of angle measurement

  

  Tilting to the left or right is measured using two areas from which the angle can be measured by subtracting.
  The external angles of both grooves and protrusions can be measured correctly.

Functions for highly accurate and stable measurements

Auto function

Simply set the workpiece and click “Auto Adjust” to automatically select the optimum shutter speed to suit the quantity of light receiving from the workpiece.

Profile correction function

The LS series is equipped with a profi le correction function that corrects workpiece position deviation in terms of height, position and tilting when compared to the registered master and is effective for production lines that create deviation of the workpieces.

Four camera modes

The LS series incorporates four camera modes for stable imaging: a standard, high resolution mode; high speed mode, which captures images at four times the standard speed; high dynamic range (HDR) mode, which increases the range of brightness; and noise reduction (NR) mode.
