Why Diamond Wire Cutting is the Best Method for Processing Germanium

Technical Articles / Bởi

If you’ve ever worked with germanium, you already know—it’s a tricky material. Dense, brittle, and not very forgiving under stress. Whether you’re producing IR optics, wafers, or custom lenses, how you cut Ge makes or breaks the result. That’s why diamond wire cutting has become the preferred method for processing germanium. Not just because it’s
