Abrégé
(EN)

The disclosure is generally directed to a method and apparatus for providing an image of a sample. The apparatus includes an illuminating source for transmitting photons to a sample. The transmitted photons illuminate the sample or are scattered upon reaching the sample. A lens collects the scattered photons and transmits the scattered photons to a tunable filter for forming an image. The illuminating photons traveling from the illuminating source to the sample do not pass through the lens.
