Abstract:
We report a scanning optical spectrometer based on the use of a stretchable elastomeric reflective
grating. The grating is obtained by supersonic cluster beam implantation of silver nanoparticles on
polydimethylsiloxane previously grooved by molding to create a replica of a commercial digital
versatile disk grating. The use of a stretchable grating allows the spectrometer spanning the whole
optical wavelength range by solely extending the diffraction element by more than 100% of its
original dimensions. The stretchable reflective optical grating shows excellent performances and
stability upon thousands of stretching cycles. The use of this elastomeric element makes the optical
layout and the mechanics of the spectrometer extremely simple and advantageous for those
applications where spectral resolution is not a major requirement. As a proof of principle, we
present the absorption spectrum of Rhodamine B in solution obtained by our spectrometer and
compared to commercial instruments.
