KODAK Electron Micrography Films
KODAK Electron Micrography Films offers considerable latitude in performance and flexibility for most electron microscopy applications. KODAK EM films are best suited for medium-energy electrons (40 to 100 ky), but acceptable results can also be obtained at higher electron levels. Specially engineered to produce high-quality images in Transmission Electron Micrography (TEM) or electron diffraction studies, there are two choices for capturing quality images in the transmission electron microscope for life and material science research.

KODAK Electron Micrography Film 4489 has approximately half the speed of KODAK Electron Image Film SO-163 film, but exhibits less curl and shorter pump-down times. Coated on a 7mils Estar support, KODAK Electron Microscope Film offers exceptional dimensional stability and eliminates the use of traditional glass support products.
KODAK Electron Image Film SO-163, two times faster than KODAK EM 4489 film, offers broad exposure and development ranges. This enables a single film to collect many electrons (with improvements in signal-to-noise ratio), or collect fewer electrons in exposure-limiting situations (when graininess is a reasonable trade-off for higher speed). SO-163’s speed requires longer pump-down times and shows greater film curl. When using KODAK Electron Image Film SO-163 for the first time, it is recommended that you recalibrate your microscope exposure.

Storing, Handling and Processing Electron Micrographs Some of the challenges confronting an electron microscopist are specimen preparation, microscopic evaluation and photographic technique. However, it is that final photographic image of the specimen which allows you to evaluate and communicate your findings. You can achieve the quality, consistency, and repeatability you require in your electron micrographs by following a few basic guidelines for storing, handling, and processing KODAK Electron Micrography Products.
Taking Better Electron MicrographsTransmission electron microscopes (TEMs) provide images with extremely high resolution for specimen analysis. The challenge is to capture these images on film without sacrificing this level of detail. The very elements that make this detail possible-the electrons- contribute to the difficulties inherent in electron micrography.
By using electrons effectively, however, it is possible to optimize image quality by maximizing density, enhancing contrast, and reducing noise.
The key is to use more electrons: in other words, to increase the sampling rate.
