紅外線 (IR) 金屬線柵偏光片

紅外線（IR）金屬線柵偏光片用於對非偏振紅外雷射光源發出的光執行偏振，以及減弱偏振紅外雷射光源發出的光。若搭配使用兩個金屬線柵偏光片，可取得超過40,000:1的高消光比。在每個偏光片的保護環表面上刻有兩道白線，以標記該偏光片的偏振軸。我們提供直紋組態與全像組態。

注意：處理KRS-5與硒化鋅時應特別小心，因為這兩者是有毒材料。請始終戴上橡膠或塑膠手套，以避免汙染危險。

Infrared (IR) Wire Grid Polarizers are manufactured by a special holographic technique that creates sub-micron wire grid spacing. Compared to conventional ruled wire grid methods, the holographic method creates finer groove spacing which optimizes short wavelength performance. We offer holographic wire grid polarizers of Barium Fluoride (BaF2), Zinc Selenide (ZnSe), Thallium Bromoiodide (KRS-5), and Germanium (Ge). 

Note: Special care should be taken when handling KRS-5 and Zinc Selenide as they are toxic materials. Always wear rubber or plastic gloves to avoid risk of contamination. The active wire-grid surface of the polarizer is extremely delicate and nothing should be allowed to touch it, as this can damage the optic. Only dry air is recommended as a cleaning method. If necessary, this optic should be handled by the edges only and with protected fingers.
