Fluidic lens and method of manufacturing the same

A fluidic lens comprising:

• a transparent substrate;
• a spacer frame which is disposed on the transparent substrate;
• a double film structure membrane which is attached to the spacer frame;
• a transparent optic fluid disposed within an inner space defined by the spacer frame between the transparent substrate and the membrane;
• wherein the inner space comprises a lens portion and a driving portion;
• an actuator, disposed on a portion of the membrane corresponding to the driving portion;
• and
• a fixing frame which is disposed on the actuator,
• wherein the membrane comprises an inner membrane comprising a transparent elastomer, and an outer membrane comprising a Poly DiMethyl Siloxane (PDMS) elastomer, wherein a coherence of the inner membrane with respect to the optical fluid is lower than a coherence of the outer membrane with respect to the optical fluid, and
• wherein a surface of the inner membrane is attached to a surface of the outer membrane.

A method of manufacturing fluidic lens, the method comprising:

• forming a first membrane, comprising a Poly DiMethyl Siloxane (PDMS) elastomer on a first subsidiary substrate and forming a second membrane, comprising a transparent elastomer, on a second subsidiary substrate;
• performing an oxygen plasma treatment on exposed surfaces of the first membrane and the second membrane;
• attaching the exposed surface of the first membrane to the exposed surface of the second membrane;
• removing the second subsidiary substrate from the second membrane;
• attaching a spacer frame, which defines an inner space, on a surface of the second membrane exposed by removing the second subsidiary substrate;
• injecting an optical fluid into the inner space and attaching a transparent substrate on an exposed surface of the spacer frame;
• and
• removing the first subsidiary substrate from the first membrane;
• wherein a coherence of the second membrane with respect to the optical fluid is lower than a coherence of the first membrane with respect to the optical fluid.
