產品系列說明

  • 對250nm - 26μm範圍內的光具有極佳的穿透能力
  • 對機械衝擊有很高的抵抗力
  • 非常適用於FTIR光譜儀
  • Sodium Chloride (NaCl) Windows Also Available

溴化鉀 (KBr) 材料常用於FTIR光譜儀。KBr的光譜範圍較氯化鈉 (NaCl) 稍大,對250nm - 26μm範圍內的光具有極佳的穿透能力。在此範圍內,其折射率介於1.46 - 1.59之間。KBr是水溶性物質,因此應防止窗口片表面暴露於潮濕環境中。若暴露於潮濕環境中,該窗口片的表面會降級。溴化鉀窗口片對機械衝擊有很高的抵抗力,可以將其輕鬆切割,能用於高達300°C的環境中。KBr的密度是2.75g/cm3,努氏硬度為7.0。
