Removing shadowing effects when using laser triangulation sensors

Shadowing occurs when the laser is blocked by a part surface while trying to return to the sensor head. The problem: Missing surface data The triangulation principle, such as the one used by laser measurement devices, often has a limitation when it comes to measuring surfaces with tall features. These tall features obstruct the outgoing …

How To Minimize Floor Vibration

Small influences make a big impact on precision measurement processes When working with sub-micron and nanometer-sized features any external vibration influence on the equipment will negatively impact resultant measurement data. External vibrations such as nearby machinery, people’s foot traffic, steady-state floor vibration, and other sources have a large impact on how clean the measurement data …

VR Stage Performance – Comparison Study

Larger travel stages from Peak Metrology maintains measurement repeatability Often, larger travel stages are needed to expand the measurement volume of VR Optical Profilers from Keyence. These measurement heads have smaller, high-precision individual fields of view, but come with software capable of stitching these smaller areas together. Overlapping data regions are used to combine the …

Removing Microscopy Field of View Limitations

The Field of View Problem Microscopes are ideal for taking measurements at high magnification. They make measuring micro and nanoscale features simple.  Specifically, measuring features within a microscope’s field of view is easy with off-the-shelf tools.  However, when the features on the part being measured are not located within the microscope’s field of view it …

Selecting a Positioning System for Your Microscope

Understanding a major limitation of microscopes The advantages of microscopy are plentiful, but they have a common limitation. The measurement field of view is small which makes it hard to measure a larger surface. That’s where an extended travel positioning system helps. Whether you are working with a digital, confocal, or structured light microscope there …

Motion Control Alignment Techniques for Part Rotation

Often, manufactured part measurement processes are impacted by misalignment between the measurement device and the part itself. Most measurement devices acquire their data in a grid or square format. Most of the time, the part being measured by these devices has its own orientation and structure to the features to be measured. A great example …
