Summary of the technology
A new illumination device suitable for optical spectroscopic characterization of optical and/or optoelectronic materials and devices. The device can tune shape and intensity of light spectrum.
Details of the Technology Offer
In some applications, optical characterization may need a narrowband light source, while in others may need broadband illumination with a specific spectral distribution, and thus a plurality of pieces of equipment for a full characterization. For example, solar cell power conversion efficiency is characterized using a solar simulator with a broadband spectrum adjusted to outdoor sunlight or others, but external quantum efficiency is measured using monochromatic wavelength illumination.
We present an innovative device that provides a tunable, focused, spectrally split beam, modulated in intensity and in a wavelength range with respect to the incoming light source. With this new device all the characterizations of optical and optoelectronic devices can be done with a single apparatus.
The apparatus works by spectrally splitting a broadband incoming light beam into its spectral components, using special prisms and custom made mirrors; then the beam passes a spatial filter stage which modifies the intensity of each color separately; finally, the beam is condensed again providing either a rainbow spot (spatially separated colors) or a homogeneous spot with the desired spectrum at all loci

About ICMAB-CSIC
The Institute of Materials Science of Barcelona (ICMAB) is a Severo Ochoa Centre of Excellence research center which beongs to the Consejo Superior de Investigaciones Científicas (CSIC) and is governed by a Foundation board.
The Institute was set up in 1987 and subsequently, in April 1991, the laboratories were opened at the Campus of the Autonomous University of Barcelona (UAB). It is part of the Barcelona Nanotechnology Cluster in Bellaterra.
The aim of the institute is to carry out research aimed at obtaining and characterising materials of industrial interest. Its activities are based on the synthesis, preparation, crystallization and characterisation of functional high-performance materials and nanomaterials, which in some cases have led to the construction of device prototypes based on these materials.
Studies and improvements both of conventional materials, as well as new molecular, supramolecular, magnetic, superconducting and porous materials etc. are being developed through projects and research contracts. There are currently 9 ERC funded projects at ICMAB.
To develop these activities, at present there are 57 permanent staff among researchers and back up personnel together with 80 non-permanent staff divided into eight researgh groups, one general unit service, and one unit of Scientific and Technological Services.
In 2016 the ICMAB reached the 100.000 citations, and it is currently the first centre, among the CSIC centres, in the Nature Index. Each permanent researcher publishes close to 5 articles per year in Journals with a very high impact factor.
