REMF Image Index

http://remf.dartmouth.edu/imagesindex.html A variety of images from the scanning and transmission electron microscopes are available for viewing via the links on this page. The images have been arranged in related series. The links here will take you to thumbnail pages for each series.
The NOAA Photo Library has been built so as to capture the work, observations, and studies that are carried on by the scientists, engineers, commissioned officers, and administrative personnel that make up this complex and scientifically diverse agency. (MORE) Meet the Photographers - The NOAA Photo collection would not exist but for the generous individuals who are willing to share their remarkable images and observations with America and the rest of the world; meet some of the men and women who have made the NOAA Photo Library possible.

Gwyddion – Free SPM (AFM, SNOM/NSOM, STM, MFM, …) data analysis

Gwyddion is a modular program for SPM (scanning probe microscopy) data visualization and analysis. Primarily it is intended for analysis of height fields obtained by scanning probe microscopy techniques (AFM, MFM, STM, SNOM/NSOM), however it can be generally used for any other height field and image analysis, for instance for analysis of profilometry data (learn more about Gwyddion features ). Gwyddion is Free and Open Source software, covered by GNU General Public License . It aims to provide multiplatform modular program for 2D data analysis that could be easily extended by modules and plug-ins. Moreover, the status of free software enables to provide source codes to developers and users, which makes the further program improvement easier. Gwyddion works on GNU/Linux, Microsoft Windows, Mac OS X and FreeBSD operating systems on common architectures, all systems can be used also for developement. http://gwyddion.net/
