In my last column I mentioned the Market Research Study: United States Testing Laboratories done by the Consulting Group at Virginia Tech with Rachel Trebour as the project manager.

As the immediate threat of Covid-19 subsides, companies are creating plans for introducing safe working practices. When it comes to sharing equipment, especially microscopes, there are concerns regarding cross-contamination and effective cleaning because most of the time an operator’s eyes come in direct contact with microscope eyepieces.

When do you need to be concerned about the effects of temperature in your inspection process, how significant is it and how do you deal with it? These can be tricky questions to answer. 

About twenty years ago I was asked to make a presentation on calibration to a meeting of a local chapter of the National Conference of Standards Laboratories.
