About This Webinar
The development of a new generation of optical components that emit, modulate, and detect light across multiple spectral ranges requires accurate tools and techniques for the characterization of these components. This is especially important for the infrared and terahertz (THz) ranges, where optical technology is less developed. Fourier-transform spectroscopy is a well-known method for the evaluation of new sources and detectors. The modern Fourier-transform spectrometer is capable of measuring spectra from the ultraviolet (UV) to the THz on a single instrument. In this webinar, an overview of experimental hardware and different approaches for detector testing and emission studies in multiple spectral ranges will be presented.

The step-scan option, for example, allows the collection of time-resolved emission with nanosecond time resolution and can discriminate between a weak emission signal in the presence of a strong thermal background. This webinar will also discuss details and optimization of the step-scan setup, including application examples for the characterization of single element and focal-plane array detectors, high- and low-temperature thermal emission, weak mid-infrared photoluminescence, laser emission, emission of micrometer-size objects, and temperature-dependent reflectance and transmittance of materials.

In particular, the presenters will emphasize challenges related to the characterization of thermal emitters that have unconventional temperature dependence, operate at low temperatures, or are out of thermal equilibrium.

Who should attend:
Developers, quality control professionals, and end users of optical instruments such as FTIR spectrometers who are interested in learning more about experimental hardware and techniques for optimizing processes across a range of applications.
