ELMI was created in 2001 to establish a unique communication network between European scientists working in the field of light microscopy and the manufacturers of their equipment.
COMULIS (together with IoP) has compiled a comprehensive imaging compendium/ textbook that covers almost 100 imaging technologies, their physical principles, typical setups, biomedical relevance & data processing schemes. It is perhaps the first ever attempt to produce a comprehensive collection of the imaging techniques used in the biological & preclinical areas.
