Optical analyzer, optical analyzing method and sample preparation device

Abstract

Optical analyzer () comprises an optically integrating cavity (), the optically integrating cavity () formed by at least one optical light diffusing wall () and adapted to contain a sample of a solid agricultural product, the sample consisting of one or more sample elements (), a light source (), emitting light into the optically integrating cavity (), whereas the at least one optical light diffusing wall () is utilized to convert emitted light to diffused light, whereas the sample at least partially or completely converts the diffused light to spectrally filtered light, and a spectral sensor (). The sample is confined in the optically integrating cavity () while the spectral sensor () is being exposed to the spectrally filtered light. Patent application has independent claims also for optical analyzing method and sample preparation device.
