The improvements that have been made with TEM have been very gradual since the 80s. Computers made them easier to use, but did not necessarily help people understand them. This guy does not have a single processor anywhere, but works extremely well. Many claim it was the best scope Philips ever made. Oh yeah, sample prep is an artform. A while back a TEM lab manager told me the best analyst he ever had was an artist. Unfortunately, I have little sample prep experience, but I aim to change that. Glad you enjoyed the read. Working on my next post tonight!
