   Dear All,   
   I explained in this short article aberration theory which is important for   
   understanding optical design process. The article will be interesting for   
   physicists and engineers that do not have strong background in optical design.   
   Please find the article in    
   the following website: http://www.mark-electro-optics.com/id19.html    
   Sincerely,   
   Mark
