Camera Length

The nominal value of the effective camera length of an electron microscope operating in the selected area mode is not sufficiently accurate for calculating lattice spacing.

All prices exclude VAT.

The nominal value of the effective camera length of an electron microscope operating in the selected area mode is not sufficiently accurate for calculating 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. The normal specimens for this are evaporated films of aluminium or thallous chloride. The very small crystallite size yields ring patterns suitable for calibration purposes. Each specimen is supplied with a list of the principal lattice spacings.
