1. Why is residual dirt analysis so important? Because we know that cleanliness is a key factor affecting reliability and service life, we thoroughly and thoroughly inspect all parts for residual particles from parts to assembly groups. Wash and clean the parts repeatedly to remove residual particle

In our engineer’s opinion,the CCD detector has better limit of detection (LOD)And CMOS has better repeatability.Let’s the comparison of them.
