Frequently Asked Questions
-
What is Potassium Bromide commonly used for?
-
Potassium Bromide is widely used in infrared spectroscopy as it is transparent to infrared light. It is also used in the manufacturing of optics, like windows and lenses, due to its optical properties. Additionally, it finds applications in medical and veterinary medicine.
-
Where can I find Potassium Bromide for sale?
-
Potassium Bromide can be purchased from chemical suppliers, online marketplaces, and companies specializing in scientific and optical materials, such as Knight Optical. Prices may vary based on purity, quantity, and supplier.
-
How does the cost of Potassium Bromide compare to other similar compounds?
-
The cost of Potassium Bromide may vary based on market demand, production costs, and availability. Generally, it is competitively priced compared to other infrared optical materials, but prices can fluctuate due to external market factors.
-
What are the main considerations when using a Potassium Bromide window in optics?
-
When using a Potassium Bromide window, consider its hygroscopic nature, meaning it easily absorbs moisture from the air. This requires careful handling and storage. Its optical properties, particularly its transmission in the infrared range, make it suitable for specific applications like IR spectroscopy.
-
How are Potassium Bromide optics typically utilized?
-
Potassium Bromide optics are primarily utilized in infrared spectroscopy and thermal imaging systems due to their excellent infrared transmission properties. They are also used in scientific research and industrial applications requiring infrared light transmission.
-
What is Potassium Bromide glass and how is it used?
-
While Potassium Bromide is not typically used to make “glass” in the traditional sense, it is pressed into windows and lenses for infrared optics. These “glass” components are essential for applications requiring the passage of infrared light, such as in IR spectroscopy and thermal imaging cameras.

Additional Information
Growth
Potassium Bromide is grown via the Kyropoulos method and cleaves easily. Though it is extremely sensitive to moisture, it can still be highly polished under humidity controlled conditions. KBr is also relatively resistant to mechanical shock.
Polishing
Potassium bromide can also be highly polished to achieve the high degree of flatness that is needed.
Considerations
Hygroscopic
Potassium bromide is very hygroscopic, so must be used in a moisture-free environment otherwise the surface of the optics will degrade.
Coatings
BBAR
We can offer broadband antireflective (BBAR) coatings for your potassium bromide.
