Product Family Description

  • Broad Transmission from 700nm - 40μm
  • Non-Hydroscopic
  • Ideal for FTIR Spectroscopy with Aqueous Samples

Thallium Bromoiodide (KRS-5) Windows provide flat transmission across the broad wavelength range of 700nm - 40μm. KRS-5 is non-hydroscopic and relatively insoluble in water, allowing for its use in FTIR spectroscopy as liquid cell windows for the analysis of aqueous samples. These windows also have good chemical resistance except against strong acids. Thallium Bromoiododide (KRS-5) Windows are ideal for use in FTIR spectroscopy, as protective windows for acid-sensitive or hygroscopic optics, or as substrates for infrared holographic polarizers.

Note: Thallium bromoiodide (KRS-5) is a toxic material that can be absorbed through the skin. Gloves must be worn while handling this material. KRS-5 has a tendency to cold flow and the shape of these optics may change over time.
