500nm Diffraction Grating Replica with Latex Spheres
magnification calibration specimen
Two-in-one; this standard for calibration provides a double-check of the accuracy of magnification calibration.
It is particularly useful at higher magnification; up to 150,000x.
The latex sphere size is 261nm and the carbon cross line grating replica with Au/Pd shadowing has a pitch or “d” spacing of 500nm or 2000 lines/mm.
Replica has well-defined trench type grooves, which makes it easy to measure the 500nm pitch.
Supplied on a G400, 400 square mesh copper grid.
