Optris pyrometers and thermal cameras are essential tools in science and engineering whenever non-contact, high-precision temperature data is needed. Researchers use them in materials science, semiconductors, energy systems, biomechanics, combustion, and aerospace to obtain accurate temperature readings and quick point measurements without interfering with the experiment.

Our thermal pyrometers and thermal cameras provide calibrated temperature data on a pixel-by-pixel basis for quantitative thermography.

These devices connect to laboratory setups through industrial I/O, free standard software, or a developer SDK, enabling automation, synchronization, and reliable data logging in experimental work. Optris offers accredited calibration and scientific support with expert knowledge to ensure the scientific correctness of the research work.

We actively support research by co-funding publication costs when the resulting paper, figures, or videos can be used as marketing material by Optris. Funding is considered case by case and requires permission to cite the work, reuse selected excerpts and images with attribution, and publish an Optris case study or highlight based on the results. To discuss eligibility and terms, please contact our team before submission.
