  • Applications

Transient spectroscopy
Through ultra-fast data acquisition, transient emission and absorption spectra during combustion processes can be captured in real time, enabling continuous monitoring of critical parameters such as temperature, species concentration, and combustion rate.

For example, Spark offers strong ultraviolet spectral response, making it suitable for engine temperature measurement. By analyzing spectral variations during combustion, combustion efficiency can be evaluated, allowing optimization measures to be implemented to reduce fuel consumption and lower exhaust emissions.

High-end on-site color measurement
By accurately capturing sample reflectance or emission spectra under high-temperature conditions, Spark enables analysis and evaluation of color characteristics based on the spectral distribution of light. It is widely used in the lighting industry, textiles and apparel, cosmetics, food and agriculture, as well as art and cultural heritage conservation. A key advantage of spectrometers in color measurement lies in their high accuracy and excellent repeatability, providing detailed spectral information for precise color analysis.

Cavity enhanced absorption spectroscopy (CEAS)
Cavity Enhanced Absorption Spectroscopy (CEAS) utilizes a high-reflectivity optical cavity to allow incident light to undergo multiple reflections, effectively extending the optical path length within the cavity and significantly enhancing weak absorption signals.

By detecting changes in transmitted or reflected light intensity using Spark, sample concentration or related optical parameters can be retrieved. This enables highly sensitive detection of trace substances in applications such as industrial process monitoring and environmental pollutant analysis.
