一般规范

colorPol® 偏振片是一种带有高对比率以及出色透射性的二向色玻璃偏振片。在标准产品系列范围中,有UV波长范围(355 - 420 nm)与VIS 以及 IR(475 - 5,000 nm)的 colorPol® 偏振片供选择。在近距红外线范围中(1200 - 2,500 nm),我们推荐您使用colorPol® HT系列偏振片,它们具有高度的透射率,最高可达98 %。

在规范的波长范围中,对比度与透射率的最小值均被保证。比如C4表示对比度 >= 10,000 : 1,也就是104。最大偏振与对比度的光谱位置可以通过所选的技术参数设置。偏振的波长范围、对比度以及透射率也可以按照客户需求个别调整。

偏振片的典型厚度为 0.2 (± 0.05) mm 到 0.5 (± 0.05) mm。更高厚度可以通过在载镜上压层来实现。CODIXX提供的压层标准厚度为 2.0 (± 0.2) mm。更多尺寸与形状可以按照客户需求来定制。

借助独特的 colorPol® 技术,CODIXX成为了世界上首家生产结构化偏振片的公司。colorPol® S偏振片具有任意成型的区域,并带有不同的定向与波长范围。10µm范围之内的结构尺寸也可供您选择。
