Abstract
The invention relates an optical probe () suitable for non-linear optics such as two-photon imaging for medical purposes. The probe has an optical guide () and a lens system () positioned rigidly at an end portion () of the optical guide. Additionally, a housing () with a cavity for the optical guide () and the lens system (), the housing having at its distal end a transparent window (), is comprised in the probe. The optical guide () with the lens system () is displaceably mounted within the housing, preferably in a transverse direction. Also, the housing () has an auxiliary, peripheral optical guide () optically connected to the transparent window (). The invention is advantageous for obtaining an optical probe with a significantly larger collection efficiency. The optical probe may advantageous be applied in connection with two-photon spectroscopy where both ballisitic photons and diffusing fluorescence photons can be used in the detection of an event.
