Applied IR Metrology - AIM -

Applied IR metrology allows for the determination of surfaces' thermal radiation as well as of radiative heat transfer through materials. The technology facilitates the comprehensive optimisation of materials and components for a vast range of applications. Additionally, in-house developed software is available for computational simulations of combined radiation and heat transport processes. The spectrum of the group includes:

Highly accurate and traceable determination of all infrared optical properties
Modelling and simulation of thermal radiation transport in materials
Development and optimisation of infrared materials and coating systems
Contactless measurement methods for characterisation and process control
Contract research and coordination of research projects
