Ditabis Micron

Classical TEM Imaging using negative film materials has been partly replaced by CCD technologies in the past 10 years. While film still produces the highest definition images on a large field of view it shows limitations in dynamics and linearity. CCD-cameras, on one hand have the advantage of producing direct digital images but on the other hand only cover a limited area at moderate dynamic range. A third alternative is Digital Imaging Plate Technology.  Although it has been around for some time, it is now available and affordable for broad use and overcomes the limitations of both technologies: The results are high definition and digital images.

Imaging Plates are nearly ideal electron detectors that give the highest quality digital Images. DITABIS Imaging Plate Technology enhances your results with all the benefits of digital imaging. By exploring the advantages of the Imaging Plate Technology the best results are obtained in resolution, linearity, sensitivity and dynamic range.

The Imaging Plate is a flexible electron detector, where an active layer of tiny crystals locally store high energy radiation.  The electron irradiation excites the crystals in their luminescence center to a semi-stable state. The image information, formed by this excitation is stable for many hours and decays within days. By an illumination with red laser light, the crystals are excited again and stimulated to release the stored information as blue luminescence signal. The amount of blue light released depends on the first excitation with electrons and is a direct measure of the electron dose. As this is a physical process it is fully reversible without degradation, so the Imaging Plate can be reused many times. By exposing to white light for a period of 10 to 15 minutes gradually all excitation is released and the plate is ready to be exposed again.
