OPTO-CH 2014  POLITEIA  thematic workshop series will introduce participants to applications of advanced laser technologies in Cultural Heritage (CH) science, diagnostics and conservation. Lectures from experts on modern laser diagnostic and analytical techniques and cleaning methodologies will be combined with practical demonstrations and laboratory hands-on sessions.


The two thematic workshops of OPTO-CH 2014  POLITEIA series are planned for the end of June- beginning of July 2014 as follows:

A.    “POLITEIA Analytical”

June 23- June 27, 2014 Advanced laser technologies for analysis, diagnostics and conservation of Cultural Heritage materials and monuments

B.    “POLITEIA Cleaning”

June 30- July 04, 2014,  Laser technologies in Cultural Heritage conservation 

Each workshop can be attended individually or participants may choose to combine them for an overall approach. Registration at each individual workshop is necessary.


The lectures will introduce participants to the general concepts and principles of operation of each technique with emphasis on their analytical and diagnostic potential and applications. Selected examples and case studies will be thoroughly analysed to illustrate how optical technologies can be used in CH conservation.
