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.

40710 - Intermediate Magnification Carbon Grating

40710 - Intermediate Magnification Carbon Grating

200 mesh copper grid. A germanium-shadowed carbon replica of a ruled diffraction grating having 28,800 lines per inch, with actual grating spacing of 882 nm.
$49.95
40720 - High Magnification Carbon Grating

40720 - High Magnification Carbon Grating

300 mesh copper grid. A germanium-shadowed carbon replica of a ruled diffraction grating having 54,864 lines per inch, actual grating spacing of 463 nm. Of particular value in high magnification work where the 28,800 line grating presents too few lines for accurate measurement.
