Dedicated image processing package for TEM

EM-MENU 3.0 is an interactive software package for advanced image acquisition and processing with an ergonomic user interface for TEM users running under Microsoft Windows NT 4.0, 2000 or XP. Images are displayed in a protected screen area using an advanced viewport concept. Optional dual display configuration enables the user to separate image and user interface.
