Diffraction Standard - Camera Length TEM Grids Pattern Size 10µm 5µm 2µmDESCRIPTION Evaporated Aluminum The nominal value of the effective camera length of an EM operating in the selected area mode is not sufficiently accurate for calculations of lattice spacing. The actual value of camera length must be calibrated at the same accelerating voltage and objective lens setting by reference to a known substance with well defined diffraction spacings. A normal specimen is evaporated film of aluminum with a thickness of around
