Rigol DHO screen protector
« on: May 10, 2026, 05:28:24 am »
It took me quite a while to find a good glass one that fits.
With the cost of these things I am surprised that they arent marketed better.

248X144MM fits the 1074

172X103MM fits the 804, but not great

Also everything I read said its impossible to cut tempered glass, but my UV laser is able to cut the screen protectors fairly successfully if its a straight cut.

Well, a laser melts stuff in a controlled manner so it kinda falls outside of what they meant by "cut". You can't use traditional glass cutting tools because tempered glass will shatter, just like you can't bend cold tempered steel. But if you heat it to a high enough temperature, then it loses its hard and brittle properties and you can rework it - though once you let it cool down it's no longer tempered steel. Same thing with the glass, except you heated it in such a localized area most of the panel is unaffected by the change.
