What are Potassium Bromide (KBr) windows?

Potassium Bromide (KBr) windows panes are common optical components suitable for various situations.

Also, they are widely used optical components in spectroscopy and infrared applications.

With an excellent transmission range of 0.25 – 26 μm, they provide outstanding performance from the ultraviolet (UV) to the far infrared (FIR) region.

Therefore, the KBr window is an ideal choice for scientific instruments, spectroscopy, and research applications.

Advantages

  • Broad Transmission Range: The Potassium Bromide (KBr) windows can be used in various situations. They are suitable from UV (0.25 μm) to FIR (26 μm).
  • Low Absorption: Minimal optical absorption ensures accurate spectroscopic measurements.
  • High Optical Quality: Polished to precise surface flatness for superior optical performance.
  • Low Refractive Index: Reduces the need for anti-reflective coatings in many applications.
  • Customizable Sizes: Chenyu can provide types of windows to fit different optical systems.

Applications of Potassium Bromide (KBr) Glass Windows

  • Fourier Transform Infrared Spectroscopy (FTIR)

KBr is a most commonly available material in FTIR spectroscopy.

Therefore, people often use them in sample cells, beam splitters, and optical windows for IR analysis.

  • Infrared and Ultraviolet Optics

UV and IR spectrometers, detectors, and imaging systems.

  • Laser Applications

Also, KBr can be used in certain laser systems where a broad spectral transmission is required, especially in the mid-IR region.

  • Scientific Research

KBr is extensively used in physics, chemistry, and environmental monitoring. Moreover, accurate transmission in the IR region is crucial for detecting gases and chemical compounds.

Also, they can provide good resistance to mechanical shock, suitable for temperatures up to 300°C.

KBr has a density of 2.75g/cm3 and a Knoop Hardness of 7.0.
