AFM Image of Cross Line Grating Replica

2,000 lines/mm cross line grating replica is suitable for X-Y calibration.

The replicas have well-defined trench type grooves, which makes it easy to determine the 500nm pitch.
The 677-AFM Grating Replica is made of cellulose acetate.
It replaces the previous #607-AFM Grating Replica with 463nm pitch.

The 677-STM Grating Replica is a carbon replica with Au/Pd shadowing supported on a 400 square mesh, 3mm copper TEM grid which is mounted on a 12mm disc.
It replaces the previous #607-STM Grating Replica with 463nm pitch.
