Thallium Bromide Iodide - KRS-5

Thallium bromide iodide, also known as KRS-5, is a crystal material commonly used as an infrared (IR) window, lens, or ATR prism in various scientific and industrial applications.

It is a type of ternary compound made of thallium, bromine, and iodine, with a chemical formula of TlBrxI(1-x), where x can vary between 0 and 1.

Properties of thallium bromide iodide

KRS-5 has many beneficial physical and chemical properties, making it an appropriate material for various uses:

​

• High transmission range - offers a wide transmission range from the mid-to far-infrared spectrum (2-40 microns).

​

• High refractive index - the high refractive index of KRS-5 permits efficient transmission of infrared light.

​

• Thermal stability - KRS-5 offers excellent thermal stability, so it won't significantly degrade in high-temperature surroundings.

​

• Chemical resistance - thallium bromide iodide exhibits great chemical resistance and stability, meaning it won't react with most acids or solvents.

​

Infrared applications

Thallium bromide iodide optics such as windows, lenses and prisms are applied across numerous infrared processes:

​

• IR spectroscopy

​

KRS-5 is an excellent material for use in IR spectroscopy and imaging due to its high transmittance in the mid-to-far-infrared range. 

​

Additionally, its resistance to thermal shock and low coefficient of thermal expansion make it suitable for use in cryogenic applications.

​

• Fourier transform infrared spectroscopy (FTIR)

​

KRS-5 is often used in fourier transform infrared spectroscopy, where it can be used as optical windows or lenses to transmit IR radiation through a sample. 

​

It is also utilised in IR imaging applications as a lens to focus IR radiation onto a detector.

​

Dangers of Thallium bromide iodide

KRS-5 is a toxic material and requires careful handling and disposal - be sure to wear industrial-grade gloves and wash your hands after touching KRS-5 optical components.

​

Due to its toxicity, it is not recommended for use in medical applications or where there is a risk of human exposure.
