The present invention relates to an optical screen element, such as a partition wall section, a glass facade, a window or the like, comprising a first glass plate and a second glass plate enclosing light manipulating means thereinbetween, wherein the light manipulating means includes a panel having a cell structure that substantially fills the space between said two glass plates and wherein the cell structure is made up by tube pieces in a polymeric material that are compactly accumulated to form a cellular panel. By a screen according to the invention, daylight is polarised, while allowing view through the cell structure parallel to its orientation. The cell structure of a screen element according to the invention allows for unhindered visual access through the screen in one direction of viewing whereas visual access is blocked from other directions. By the optical effect of the screen element of the invention, a new design possibility is offered not only to engineers and building designers but also interior decorators, since it is realised that the screen element can be used for several purposes besides glass panels and facades such as a partition wall, a dividing screen within an office space or the like. Moreover, the polymer material cellular structure makes the cellular panel easy and inexpensive to manufacture. |
