DIMMER AND METHOD OF INSTALLING DIMMER
PROBLEM TO BE SOLVED: To provide a dimmer capable of switching between a transparent state and a reflective state for infrared light.SOLUTION: This invention provides the dimmer comprising a first dimming control panel and a second dimming control panel movable relatively to the first dimming control panel. The first and second dimming control panels include polarizers, and the polarizers include a plurality of unit regions into which the polarizers are divided in a relative movement direction of the first and second dimming control panels, and the plurality of unit regions are divided to first to n-th groups in the order of arrangement in the relative movement direction, and transmission axes are parallel among unit regions belonging to one group, and transmission axes are not parallel among unit regions belonging to different groups, and the polarizers of the first and second dimming control panels are wire grid polarizers, and each of the wire grip polarizers includes: a transparent relief structure layer with recessed and projecting faces arrayed with a pitch within a range of 300 nm or more and 500nm or less and formed by a plurality of linear projections; and a metal layer provided on at least a part of the linear projections.SELECTED DRAWING: Figure 1
【課題】赤外光のみについて透過／反射の各状態を切替可能な調光装置を提供すること。【解決手段】本発明は、第１調光制御パネルと、第１調光制御パネルに対して相対移動可能な第２調光制御パネルとを備え、第１及び第２調光制御パネルは偏光板を含み、偏光板は第１及び第２調光制御パネルの相対移動方向に当該偏光板を領域分割してなる複数の単位領域を含み、複数の単位領域は、相対移動方向に並べられた順番で第１〜第ｎ群に振り分けられ、一つの群に属する単位領域の間で透過軸は平行であり、異なる群に属する単位領域の間で透過軸は非平行であり、第１及び第２調光制御パネルの偏光板はワイヤーグリッド偏光板であり、ワイヤーグリッド偏光板は、３００ｎｍ以上５００ｎｍ以下の範囲内のピッチで配列され且つ複数の線状凸部によって形成された凹凸面を有する透明凹凸構造層と、少なくとも前記線状凸部の一部分上に設けられた金属層と、を含む調光装置である。【選択図】図１
