At the JCK Show in Las Vegas, I found a Meiji EMZ 5 microscope sitting right next to a Chinese knock-off. It was a rare chance to do a side by side comparison under identical light. No ring lights were used...only ambient room light.
As you can see in the photo, the Chinese scope has a yellow tint. This is the result of cheap manufacture and not using optical glass.
Granted this is not a scientific comparison. It was 2 shots with my iPhone. But the photos are a clear indication of inferior optics.
