Overview of our range of time-domain spectrometers

definition 

time-domain spectrometer analyze the spectral properties of materials or events by examining the temporal evolution of a signal after excitation. These devices measure how the intensity of light changes over time after the sample has been excited with a short light pulse. Thus, they provide spectrometer Information about the dynamics of processes on very short time scales.

Comparison with other spectrometer types

Next to Time-domain spectrometers Other types of spectrometers also exist. Frequency domain spectrometers analyze light in its various frequency components. Photon counter spectrometers detect individual photons to measure very weak light signals. In contrast, these focus on the temporal characteristics of the light.

functionality 

time-domain spectrometer They typically work with short laser pulses that excite the sample. The temporal response of the sample is then detected. This can, for example, be the measurement of the fluorescence decay behavior or the temporal delay and change in the intensity of a transmitted or reflected pulse. The analysis of this temporal data allows conclusions to be drawn about the spectral properties of the sample.

Advantages 

time-domain spectrometer offer advantages for specific applications. They enable the direct measurement of time constants and lifetimes of excited states. This is particularly useful for the investigation of photophysical and photochemical processes. Furthermore, in certain cases, they can offer higher sensitivity or better spectral resolution compared to other methods.

Areas of application 

time-domain spectrometer are used in various research areas. These include the measurement of fluorescence lifetimes in biochemistry and materials science, the investigation of ultrafast processes in physics and chemistry using pump-probe spectroscopy, and optical coherence tomography (OCT) in medical imaging.

Selection criteria 

When selecting a suitable spectrometer The specific requirements of your application should be considered. These include the required time resolution, the relevant wavelength range, the sensitivity of the detector, and the type of excitation source. Our experienced team offers support in selecting the optimal spectrometer for your measuring tasks.
