The invention provides an endoscope or microscope (10), comprising: an optical fiber (20) for transmitting a pulsed main beam over at least a portion of an optical path between a beam source (12) and a tissue (44) or other sample and a dispersing device (28, 30), wherein dispersion occurring in the optical fiber is reversed by dispersion generated by the dispersing device. The invention further provides an endoscope or microscope (10) with a head (40), the endoscope or microscope comprising: a suction or negative pressure source, which is arranged near the head, a light collecting device for collecting light from a sample and one Sample receiving means, coupled to the suction source, for receiving the sample when the sample is pressed against it by the suction source, the suction source being used to push the sample to the receiving means, thereby deforming the sample so that the light receiving means becomes part of the light emitted by the sample away from the head. |
