Testing of the measurement of flame temperature using FlameMaster
Calibration setup using a filament lamp

LaVision’s Two-Color Pyrometry setup provides a robust system for temperature measurements. It demonstrates the precise measurement of flame temperature, showcasing the system’s accuracy and capability. Additionally, the calibration process is conducted using a filament lamp, ensuring the system’s reliability and accuracy through meticulous calibration procedures.

The FlameMaster inspex imaging systems apply flame emission spectroscopy to combustion processes.

​The flame emission (chemiluminescence) of flame radicals like OH*, CH*, C2* is used to e.g. visualise the reaction zone or to monitor flame stoichiometry via emission ratios of such radicals. 2-colour pyrometry (blackbody radiation) is used to measure temperature fields in sooty flames.

Emission Spectroscopy: Spectral Imaging

Based on emission spectroscopy flame emission is analysed using spectral imaging. Flame emission imaging is a line-of-sight method like absorption and probes electronically excited species in contrast to LIF which probes ground state species. 2D flame species imaging is carried out with a set of filters mounted in front of the camera lens or 1D using an imaging spectrograph for correlated multi-species detection.


The flame emission (chemiluminescence) of flame radicals like OH*, CH*, C2* is used to e.g. visualize the reaction zone or to monitor flame stoichiometry via emission ratios of such radicals. Infrared emission visualises major flame components like unburnt fuel, CO2 or water.


2-color pyrometry (blackbody radiation) is applied to measure temperature fields in sooty flames. Temporal flame analysis (flame flicker) is measured using statistical information from a time series of flame images. High speed imaging is applied for flame propagation and extinction measurements.
