Quality control applications that require precise measurement can be some of the most challenging applications to solve. Very tight tolerance requirements demand a reliable solution that can measure parts in micrometers to detect the smallest variations in part size, thickness, orientation, placement, and more. Ensuring parts meet strict quality standards can help reduce problems downstream and reduce the risk of product recall due to imperfect parts.
Laser measurement sensors are a common solution for precise part inspections. However, real world conditions—including variations in target color and reflectivity, fluctuations in ambient temperature, and vibration from improper mounting—can make precise measurement challenging, even for laser sensors that perform well in perfect laboratory conditions. Therefore, it is important to understand the factors that can impact measurement precision in order to identify a solution that can overcome these challenges.
