Hello Sanjay! The cheap deal I use that Earl spoke of is called a SMarT Measure. It's a depth measuring microscope that uses the same principle of measuring optical focus that the units from Vision Engineering do ( if you've ever looked at any

Steve, Whoa, take a breath! That was at least a dollar three-eighty answer. I've got to agree that nothing can replace a qualified, concientious operator for assuring quality. When I too worked at a small shop there in SillyCone Valley, my seni
