Application of tot’hema eosin sensitized gelatin film for adaptive microlenses

In this paper we showed that tot’hema eosin sensitized gelatin (TESG) film can be used for adaptive microlenses fabriacation. The mechanical properties of a pure gelatin film were improved by adding tot’hema solution. We found that the elasticity of TESG film depend on the tot’hema concentration. By...

Zusammenfassung:In this paper we showed that tot’hema eosin sensitized gelatin (TESG) film can be used for adaptive microlenses fabriacation. The mechanical properties of a pure gelatin film were improved by adding tot’hema solution. We found that the elasticity of TESG film depend on the tot’hema concentration. By stretching the film, the microlenses were deformed uniaxially, and microlenses focal length can be tuned. The achieved microlenses focal lengths range from 0.05 to 0.2 mm.
