Which Optical Measurement Sensor is the Best? A Guide for Choosing the Most Appropriate Sensor for Non-contact Measurement

The demand for precise optical measurement sensors is rapidly increasing due to the need to measure displacement, thickness and dimensions with micrometer precision. But which sensor is best suited to which application? This webinar explains technologies, differences and application examples for optical measurement sensors: confocal, laser triangulation and 2D/3D profile sensors.

Time: 10 AM EDT (7 AM PDT)
Duration: 1 hour

Optical sensors are increasingly used for precision measurement due to many factors: on the one hand, the need to measure displacement, thickness and dimensions much more accurately with micrometer resolution, and on the other hand the need to measure against fragile surfaces that cannot be touched.

Their rapid growth in the sensor market has pushed the development of new technologies to meet demanding requirements and to improve measurement accuracy. It is therefore more important than ever to have a greater level of understanding of the strengths and limitations of each optical measurement principle when selecting the correct sensor technology for your specific measurement task. The key is selecting the most appropriate sensing technology for your measurement task.

This webinar explains different technologies, restrictions and differences of the following technologies: confocal chromatic sensors, laser triangulation sensors (and even time of flight sensors) and laser profile sensors including the innovative blue laser technology. All these sensors are used for measurements with high precision, stability and high measuring rates.

Attendees will learn the operating principles of optical measuring sensors for displacement, position, thickness, gap, profile and 2D/3D dimension with just one sensor. Various animations and graphics show detailed application examples and give important tips for choosing the right technology. Additional resources for further details are provided by Micro-Epsilon.
