Abstract: A miniature stacked glass lens module is disclosed. The miniature stacked glass lens module includes at least one stacked optical glass lens element, a lens holder and other optical element. The stacked optical glass lens element is formed by cutting along alignment notches on a glued and stacked optical glass lens array. Then the stacked optical glass lens element and other optical element are mounted into the lens holder to form a miniature stacked glass lens module. Thereby the precise alignment of the optical axis of the lens in the lens module can be achieved. The manufacturing processes of the lens module can be simplified dramatically and the manufacturing cost is reduced significantly.

Abstract: Ethylene and allyl- or vinylsilanes are efficiently copolymerized by certain late transition metal complexes containing selected bidentate or tridentate ligands.
