產品系列說明

  • 在 0.25 - 26μm 範圍內穿透率出眾
  • 具有良好的抗機械衝擊能力
  • 是傅立葉轉換紅外光譜的理想選擇

ISP Optics 溴化鉀窗鏡在從深紫外(DUV)到長波紅外(LWIR)的寬波段範圍內穿透率出眾。這些窗鏡具有很強的抗機械衝擊能力,易於切割,可在高達300℃的溫度下使用。溴化鉀是水溶性的,應避免暴露於潮濕和高濕度的環境中,會使窗鏡的表面產生退化。ISP Optics 溴化鉀窗鏡可用於紫外(UV)、可見光(VIS)、中波紅外(MWIR)和長波紅外(LWIR)光譜的廣泛應用,尤為適用傅立葉轉換紅外(FTIR)光譜。

請注意:溴化鉀(KBr)是水溶性的,一定不要在潮濕的環境中使用。
