fig1 shows a microscope according to the invention , which is configured as a confocal scanning microscope , having a microscope objective 1 with an optical fiber 3 . this optical fiber 3 has an outcoupling end 5 arranged inside the microscope objective 1 , namely , in a fourier plane 9 that is conjugate to the focal plane 7 of the microscope objective 1 . the scanning microscope has a light source 11 configured as a multiline laser 13 . the illumination light 15 generated by the illumination light source 11 is deflected by a main beam splitter 17 to a beam deflector 19 that comprises a gimbal - mounted scanning mirror 21 . in order to scan the specimen , the beam deflector 19 guides the illumination light through the scanning optical system 23 , the tube optical system 25 and through the beam splitter 27 as well as through the microscope objective 1 or through the specimen 29 that has been placed on a specimen slide 31 . the detection light 33 coming from the specimen 29 travels along the same light path , namely , through the microscope objective 1 , through the beam splitter 27 , the tube optical system 25 as well as through the scanning optical system 23 , returning to the beam deflector and to the main beam splitter 17 , then it passes through the latter and through the subsequent detection pinhole diaphragm 35 , finally reaching the detector 37 that is configured as a multiband detector . in order to attain an evanescent specimen illumination ( tirf illumination ), the illumination light 15 is deflected by the beam deflector 19 through the scanning optical system 23 onto the incoupling end 39 of the optical fiber 3 . the incoupling end 39 is in a plane 41 that corresponds to the focal plane 7 of the microscope objective 1 , namely , an intermediate image plane 43 . the illumination light 15 that is coupled into the optical fiber 3 runs through the edge region of the microscope objective 1 and exits from the front lens 45 at an oblique angle relative to the optical axis of the microscope objective 1 . this angle can be adjusted by changing the distance of the exit end 5 from the optical axis 47 of the microscope objective 1 . the microscope objective 1 is optically coupled to the cover glass 31 via an immersion medium 49 . in order to generate an image of the evanescently illuminated specimen 29 , a camera 51 is on hand that receives the additional detection light 53 that comes from the specimen , passes through the microscope objective and is deflected by the beam splitter 27 to the camera 51 . fig2 shows another microscope according to the invention that is likewise configured as a confocal scanning microscope . in this embodiment variant , the beam splitter 27 that deflects the additional detection light 53 to the camera is arranged above the intermediate image plane 43 . the invention was described with reference to a specific embodiment . however , it goes without saying that changes and modifications can be made without departing from the scope of protection of the claims presented below .
