Prisms of vitreous carbon

Polished and labelled carbon in 02751-AB mount

Here you see reflected light micrographs of polished and coated carbon. The identifying etched label, which is a feature of our standards, is invaluble when navigating in a beam instrument. Vitreous carbon is harder than graphite, which we used in our standards in earlier times, and therefore polishes better.

At the right is a reflected light micrograph of polished, carbon coated graphite. The identifying etched label, which is a feature of our standards, is invaluable for navigating in an electron beam instrument. This form of carbon is extremely soft and therefore polishes very poorly.
