VARIABLE FOCUS LENS PACKAGE HAVING CLAMPING MEANS FOR FIXING THE VARIOUS LENS PACKAGE ELEMENTS WITH RESPECT TO EACH OTHER |
摘要 |
A variable focus lens package ( 2 ) comprises an annular body ( 10 ) having a through-hole ( 11 ), which is closed off by means of lens members ( 30, 70 ), and which is sealed by means of sealing rings ( 50, 60 ). The through-hole ( 11 ) is filled with quantities of water ( 86 ) and oil ( 87 ), which are separated by a meniscus ( 88 ). The various lens package elements are fixed with respect to each other by means of clamping units ( 20 a , 20 b). By this arrangement, a very compact and robust lens package ( 2 ) is obtained. A portion of the surface of the body ( 10 ) is covered with an electrically conducting layer ( 16 ). The shape of the meniscus ( 88 ) is variable under the influence of a voltage between this electrically conducting layer ( 16 ) and the water ( 86 ). In this way, the meniscus ( 88 ) is applicable as a lens having an adjustable focus. |
