METHOD FOR OBSERVING A SAMPLE IN TWO SPECTRAL BANDS, AND AT TWO MAGNIFICATIONS

摘要

Device for observing a sample, comprising:a light source configured to emit an incident light wave in a first spectral band and in a second spectral band, the first spectral band being different from the second spectral band;an image sensor comprising a first group of pixels, which are sensitive to the first spectral band, and a second group of pixels, which are sensitive to the second spectral band;a holder configured to hold the sample in a holder plane, the holder plane lying between the light source and the image sensor, such that when the sample is held by the holder, under the effect of its illumination by the incident light wave, a light wave of interest propagates to the image sensor;the device being configured to direct, to the image sensor, a first component of the light wave of interest, in the first spectral band, and a second component of the light wave of interest, in the second spectral band.
