Abstract
Official abstract text for this publication.
Embodiments of the present invention include a cuvette ( 100 ) for use in determining a refractive index of a sample matter in a spectrophotometer ( 600 ), the cuvette comprising a container ( 102 ) for holding the sample matter, the container ( 102 ) having an entry window ( 121 ) that allows input radiation to reach the sample matter, the container furthermore having an exit window ( 122 ) that allows a part of the input radiation to exit the container part, the entry window and the exit window defining a radiation path; and comprising a photonic crystal ( 101 ) rigidly attached to the container or integrally formed in the container and arranged in the radiation path, the photonic crystal having a grating part ( 111 ) causing a reflectance spectrum of the photonic crystal to exhibit a resonance. A spectrophotometer is also provided.
First claim
Opening claim text (preview).
The invention claimed is: 1. A cuvette configured to determine a refractive index of a sample in a spectrophotometer, comprising: a container for holding the sample, the container having: a square footprint defined by a bottom wall, four side walls and an opening arranged opposite the bottom, an entry window arranged in a first side wall that allows input radiation to reach the sample, the container furthermore having an exit window arranged in a second side wall opposite the f…
