A mirror with slidable set is disclosed having a primary mirror with a back surface and a slidable set integrated to the back surface. The slidable set includes at least one lever pair fixed with an articulated joint to the back surface of the primary mirror. An opposite end of the at least one lever pair is fixed with an articulated joint to at least one moveable element that is mounted slidably on at least one guide. The at least one guide is placed parallel to the back surface of the primary mirror and at a horizontal height generally the same as the horizontal height of the ends of the at least one lever pair. The moveable element is joined to a driving unit. The driving unit may comprise an electric motor with a switching on/off unit, a pneumatic actuator or a hydraulic actuator.
