Software for running a time-resolved spectrometer.

Project description

TRSpectrometer is a platform for time-resolved spectroscopy, encompassing both software and hardware designs. It can be used for both data acquisition, as well as viewing data and basic analysis.


  • Completely open source hardware and software designs. Don’t get stuck with inflexible and buggy proprietary software!

  • Plugin architecture to ease modifications and integration of new hardware devices or experimental methods.

  • Supports the latest rapid-acquisition techniques.

  • Cross platform python - Linux, Windows, MacOS.

The aim of the software is to be as open and flexible as possible, using a plugin system for the addition and customisation of features and functionality. For example, the same software that runs on a Windows machine acquiring data can be installed on a Linux or Mac OS computer and used for data viewing and analysis without restriction. The majority of the code base is written in Python, making development and modifications (hopefully!) more accessible to students and researchers who lack specific programming backgrounds.

The initial 1.0 version includes a reference hardware design for a transient absorption (pump–probe) spectrometer and a cross-platform software application for data acquisition and basic data exploration and analysis. In time, it is hoped that the platform will support a wider variety of hardware and additional time-resolved experimental techniques, as well as adding more advanced data exploration, analysis, and plotting tools. This will only truly be possible through contributions by users and other interested parties. See the Contributing page in the documentation for more information.


The latest release can be downloaded and installed using the Package Installer for Python (pip):

pip install --upgrade trspectrometer

On Linux, a launcher icon should be installed in your menus (this feature is not yet implemented on Windows or MacOS). On all operating systems, the application can be launched from the command line:
