Fluid　mechanics　principle　about　the　optic　micro-lens　generated　on　needing　positions　is　researched.　A　set　of　surface　equations　of　optic　glue　drip,　which　spreads　on　horizontal　plane　under　surface　tention,　is　given.　The　equations　set　reflect　relationships　between　coordinates　of　an　arbitary　point　on　the　surface.　A　numerical　calculation　method　of　the　equations　set　is　proposed.　Some　surface　shape　parameters　of　the　glue　drip　are　calculated　for　different　performance　parameters,　such　as　volume,　contact　angle　and　character　length.　Some　shape　curves　and　curvature　radius　curves　are　given.　Results　show　that　the　contact　angle　and　character　length　decrease,　spread　radius　increase　and　thickness　decrease,　and　non-sphere　performance　is　strengthened.　The　intensity　of　the　micro　lens　increases　and　the　contact　angle　and　character　length　decrease　by　mixing　appropriate　amount　nanometer　quartz　powder　into　the　glue.　The　bond　strength　between　the　glue　and　the　glass　increases　and　the　contact　angle　decreases　by　milling　or　roughing　the　glass　face.
