   Hi,   
      
   The reason why I prefer not to use c-mount is to save cost ;   
   but if at the end it happens that the customized solution makes   
   it more expensive I will change my mind. But I would like first   
   to be sure if there is no solution with mounting lens on top   
   of the sensor.   
      
   I have started doing a Zemax plan with two spherical lenses ;   
   one divergent and one sphere of 2.5mm radius.   
   Here is the drawing :

   Do you have reccomendations for professional ?   
   What's your personal email ?   
      
   Thanks,
