09 Apr 2009 Specac Ltd. has introduced a value range of holographic wire grid polarizers for IR applications. These are provided on Barium Fluoride (BaF2), Calcium Fluoride (CaF2), KRS-5, and Zinc Selenide (ZnSe) substrates, and are manufactured at 2500 lines/mm to provide excellent polarization performance at an economical price. They are sold from stock, and are available in standard sizes of 25 mm or 50 mm diameter. Common uses include: the polarization of radiation for unpolarized sources, attenuation of radiation from polarized sources, or acting as polarizing beamsplitters. Further applications include infrared spectroscopy of materials and NIR/Mid-IR thermal imaging, amongst others. These polarizers are offered in addition to Specac's range of standard and high extinction ratio IR polarizers. |
