Hi!

One possibility is to use micro hardness indents with a indentation force adjusted to the hardness of your sample!

Good luck!

Have you considered using a laser to etch the surface?

Varadaraju Magesh

No sir, You mean laser engraving?

Yes, you could call the technique laser engraving. But I understand you only want a micron size dot.

Thanks sir. I want micron size dot only as a reference for measurement.

Santosh Sadashiv Todkar

Hello sir,

Nano indentation will help you, to put accurately put up 0.001mm dent or dot.
