Optical micro plugs for multichannel and multilayer pharmaceutical device

A ceramic micro well plate comprising:

• a first ceramic greensheet;
• a first plurality of vertical openings in said first ceramic greensheet, said first plurality of vertical openings in said first ceramic greensheet being a plurality of reaction chambers;
• a second ceramic greensheet;
• a plurality of horizontal openings in said second ceramic greensheet, selected ones of said plurality of horizontal openings connecting selected ones of said first plurality of vertical openings;
• a third ceramic greensheet;
• a second plurality of vertical openings in said third ceramic greensheet aligned with said first plurality of vertical openings in said first ceramic greensheet;
• and
• a plurality of optical micro plugs in said second plurality of vertical openings, said plurality of optical micro plugs aligned with said first plurality of vertical openings to allow viewing of said reaction chamber of said micro well plate.

A method of forming a ceramic micro well plate comprising:

• providing a first ceramic greensheet;
• forming a first plurality of vertical openings in said first ceramic greensheet, each of said first plurality of vertical openings in said first ceramic greensheet being reaction chambers of said micro well plate;
• providing a second ceramic greensheet;
• forming a second plurality of vertical openings in said second ceramic greensheet;
• aligning said first plurality of vertical openings in said first ceramic greensheets with said second plurality of vertical openings in said first second ceramic greensheet;
• and
• depositing an optically effective material into said second plurality of vertical openings in said second ceramic greensheet to form a plurality of optical micro plugs, whereby said optical micro plugs allow viewing of said reaction chambers of said micro well plate.
