I bought some LaB6 from gem dugout.   thegemdugout.com
There datasheet references calibration against NIST SRM-640C.

I'm still looking for a source of corundum, though.

Hi All,

Does anyone know an appropriate source of standard reference materials for a line profile standard, like NIST SRM 660a (LaB6) - other than NIST, as they are out of stock and "...is expected to become available by November 2009."

Thanks,

Ross
