Good Metallurgical Microscope?
Good Metallurgical Microscope?
(OP)
Skyrocketing prices for met lab services are forcing me to consider setting up my own basic metallography capability. This would support failure analysis, so not an everyday tool, and it just needs to do the job: capture good quality images for evaluation and reporting purposes. The subject matter is usually not very exotic - carbon steel, stainless steel, weld sections, etc.
As much as I would love an all-dressed Zeiss or Nikon (at prices equivalent to a substantial down-payment for a house), I can't get close to those. So I am looking at 'Amscope', and want to know if anyone has experience with this low-priced Chinese scope and camera combo. A little googling shows that the same equipment is sold under different names (no surprise if you spend any time on Amazon).
Thanks in advance.

They are pleased with it.

Not very expensive.
Buy a good camera, speed and color depth are more important than raw resolution. And get good software for image analysis, try them and see what you are comfortable with.
You will likely want a good binocular scope for <50x macro work. Olympus makes the best, but they are pricey so look for a used one.

RE: Good Metallurgical Microscope?
We've had the same thought few years ago, and went through the same research. Visited the two labs we usually work with, and started acquiring materials as we went.
You'll need a band saw with a decent capacity (you'll always come home with a piece that doesn't fit inbetween the jaws), a press and base material to fit small pieces in a resin block (don't know the english word), a sanding/polishing table, lots of different grits, a selection of etchants (of which you'll use not enough, and end up throwing away lots of it because some expire fast after mixing), and finally the microscope. And because we work with some exotic materials, we'd also need HF, which is more or less potentially deadly, and NaOH, which without fume extractor cannot be used indoors. And outdoors is still not the best idea...
Dino-Lite makes a great USB alternative, which would probably offer you some versatility for DIY-work for around USD500. Works decent, after freehand grinding with a random orbit sanding machine with lots of different pads.
True micro/macrography should be sent out to a dedicated lab... my $ 0.02.
