80051, GRATING REPLICA CROSS LINE

Grating Replicas: Parallel and Crossed Lines

Parallel: Shadowcast carbon replicas of diffraction parallel line gratings with spacing of 462.9nm, 2160 lines per millimeter onto 3.05mm grid.

Crossed: Cross line pitch spacing of 463nm with 2160 lines/mm in both directions, cross at 90° to one another give additional accuracy to magnification checks and aid in checking distortion. Trench-type groove makes it easy to measure pitch. Ideal for calibration electron-optical magnification up to the x80000/100000 range.
