Optical device and a method for manufacturing the same

A method for manufacturing optical devices, comprising:

• (A) connecting a frame unit defining a plurality of hollow regions to a base seat unit;
• (B) connecting a plurality of optical elements to the base seat unit;
• (C) connecting a plurality of spaced-apart lenses to the frame unit to respectively cover the hollow regions, and forming a gap among the lenses, each of the lenses having a first surface that faces the base seat unit and a respective one of the optical elements, a second surface opposite to the first surface and a side surface interconnecting the first and second surfaces of the lens;
• (D) filling a first adhesive layer into the gap among the lenses, the first adhesive layer being connected to the side surfaces of the lenses and the frame unit and defined with a plurality of intersecting scribing lines which define boundaries of the optical devices;
• and
• (E) dicing the first adhesive layer, the frame unit and the base seat unit along the scribing lines.
