2160 lines/mm Shadow cast carbon replicas of diffraction line gratings, single direction lines -
Negatively stained catalase crystals show lattice plane spacings of approximately 8.75nm and 6.85nm very clearly (using TEM and STEM). (Figures determined by Wrigley. J. Ultrastructure Res. 24, 454. 1968). They are valuable for high magnification calibration. -
Combined test specimen -
2160 lines/mm Shadow cast carbon replicas of diffraction line gratings, Cross Direction -
Diffraction grating replica with latex spheres -
Evaporated Aluminium Film 3mm; 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. -
Evaporated platinum / iridium, 3.05mm grid; The evaporated platinum/iridium specimen is supplied on a perforated carbon support film that provides holes for ease of focus and astigmatism correction. -
High resolution test specimen gold particles on carbon film -
Image rotation, Molybdenum trioxide crystals -
Mag*I*Cal calibration standard -
Perforated carbon film, 3.05mm grid. This specimen is one of the quickest and easiest to use for performance checks since it gives information about nearly all causes of loss of resolution. -
Standard for HVEM; Normal resolution test specimens are difficult to see on the viewing screen because of low contrast. -
Xray standards for TEM; These standards are supplied as fine powders dispersed onto holey carbon films and are selected from a range of certified materials and synthetic compounds. -
