VARIABLE LENSES FOR OPTICAL DIGITAL MODULES |
摘要 |
The invention relates to a variable lens comprising at least two optical elements, wherein at least one of the optical elements is movable in a plane transversely of the optical axis of the lens relative to the at least one remaining element, wherein at least two optical elements have a surface described by a polynomial of at least the third order, and wherein the curvature of the curved surfaces of the optical elements is such that at different relative positions of the displaceable optical elements the resulting lens has a differing strength. According to a first embodiment, the lens comprises at least one optical element having at least one surface described by z = S<SUB>A</SUB> (x,y) = A(x<SUP>2</SUP>y<SUP>2</SUP> + x<SUP>4</SUP> / 6). According to another embodiment, the lens comprises at least one optical element having at least one surface described by z = S<SUB>c</SUB>(x,y) = C(x<SUP>2</SUP>y<SUP>3</SUP> + x<SUP>5</SUP> / 10). |
