Application

The Potassium bromide crystal optic disc, measuring 13mm x 2mm with both sides polished, serves a pivotal role in the field of infrared spectroscopy and optical applications. This disc leverages the unique properties of potassium bromide, a material known for its low refractive index and expansive spectral range extending into the infrared spectrum with minimal absorption. In practice, this makes the potassium bromide disc an excellent choice for use as an infrared optical window and substrate for interferometers, where it facilitates the accurate transmission of infrared radiation. The disc can be used to suspend powder samples in transmission infrared spectroscopy, thus enabling detailed analysis without interference in the transmitted signal. Embracing this crystal's optical capabilities, the optic disc supports various scientific investigations and applications, ensuring precision and clarity in infrared spectroscopic measurements.
