產品系列說明

  • 專為2 -30μm的波長範圍而設計
  • 提供多種基材的全像偏光片供選擇
  • 使用 公制偏振鏡支架 進行360° 旋轉

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。

紅外線 (IR) 線柵偏振片採用專業製程製造,以實現亞微米線柵間距。與傳統分格線柵法相比,全息法可產生更細的凹槽間隔,從而優化短波長性能。我們的紅外線 (IR) 線柵偏振片材質有氟化鋇 (BaF2)、硒化鋅 (ZnSe)、溴碘化鉈 (KRS-5)和鍺 (Ge)。

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。偏振片的有源線柵表面非常脆弱,任何東西都不能接觸,否則會損壞光學元件。建議只用乾燥空氣進行清潔。如有必要,只能用邊緣和受保護的手指操作該光學元件。

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.
