Invention:
This technology is a programmable light source that can synthesize an arbitrary spectrum and polarization state. The instrument can be utilized as a tunable light source, spectrum equalizer, polarization compensator, wavelength scanner, and polarization state generator, in applications where control of the output polarization state of the light is required. Applications include telecommunication, 3D imaging, biomedical imaging, microscopy, remote sensing, ellipsometry, polarimetry and spectroscopy.
Background:
A Tunable Light Source or TLS is used to maximize throughput in the visible region of the spectrum to study wavelength dependent chemical, biological, and physical changes, or properties. It can also be used in color analysis and reflectivity measurements of products for aesthetic purposes. The TLS is great for laboratory use and can be customized for many OEM applications.
Many types of TLS are available, with differences in individual component performance translating to the performance of the system. TLS are finding themselves to be an especially ideal system for one application in particular: quantum efficiency and spectral responsivity characterization of photonic sensors, such as solar cells. The TLS versatility as both a broadband and high-resolution monochromatic light source makes the unit suitable for a variety of applications, such as the study of wavelength-dependent chemical or biological properties or wavelength-induced physical changes of materials. These light sources can also be used in color analysis and reflectivity measurements of materials for quality purposes.
