Re: Scratch resistance of glass

Hello Group,

I have a question to which some of you may know the answer.

Does glass with antireflection coating provide greater resistance
to scratching than pure glass?

Which of the following two glasses is more scratch resistant:
BK7 or B270?

Thanks for any replies.

The anti-reflective coating is different from glass, it helps the
light transition from one low refractive index to another higher one.
Most coatings are harder than the glass it sits on. Now thats most.
Check the web sites of glass manufacturers like Corning, they will
list all the characteristics of each glass they make to mind numbing
standards.
