EM-Tec TC1 TEM calibration standard oriented gold crystal

Description

Oriented gold crystal provides plane spacing of 0.102, 0.143 and 0.204nm. Used for checking resolution, image quality, magnification and instrument stability in high resolution TEMs. The single oriented gold crystals produces a characteristic diffraction patterns. When the TEM is correctly setup, it should resolve the 0.102 nm (100 plane) planar spacing, 0.143 nm (220 plane) and the 0.204nm (200 plane). Since these are physical constants they can also be used for magnification calibration. Mounted on a 400 mesh Au TEM grid.
