Olympus is introcluced their new Diffusion Measurement module for Olympus ASW 2.1 software. Designed specifically for use with the Olympus FluoView FV1000 confocal microscope system for live cell imaging this new software module provides users with the flexibility to undertake three different types of diffusion study: point fluorescence correlation spectroscopy, raster scan image correlation spectroscopy (RICS) and fluorescence recovery after photobleaching (FRAP). As a result, the Diffusion Measurement Package can be used for a broad range of cell biology and biophysics applications.
