Buy Carbon Gratings Online

Our carbon gratings are made from the highest quality diffrection gratings. They are useful in the electron microscope to obtain accurate magnifications of specimen negatives at identical microscope settings. Their accuracy and reproducibility have been attested to by an independent research organization. Variations over long periods of time have not exceeded 4 per cent.

We recommend that the carbon grating be mounted on the same type grid as the specimen. A magnification chart and full directions for use are included with each carbon grating. All calibration and test specimens are available on athene-type grids of copper, nickel or gold. Standard grid is listed with each item. Other mesh or material is available on request.
