Microscope for reflected-light and transmitted-light microscopy
View Patent ↗A microscope is disclosed in which a specimen is arranged between two objectives and can be observed with reflected light as well as with transmitted light. In a microscope with field transmission, two objectives have substantially identical optical characteristics and at least one of the two objectives is followed by a mirror which reflects the light transmitted through the specimen back into itself exactly. In this way, there is twofold transmission through the specimen with optimum illumination of the solid angle. In a laser scanning microscope, there are likewise two objectives with substantially identical optical characteristics and at least one of the objectives is followed by a phase-conjugating or adaptive mirror.
1. A microscope comprising:
two objectives between which a light-transmitting specimen is arranged;
said objectives having at least substantially identical optical characteristics; and
at least one of said two objectives being followed by a mirror for reflecting light transmitted through the specimen back into itself exactly;
wherein another mirror is provided between one of said objectives and an eyepiece, the specimen being imaged on the another mirror through said one of said objectives, wherein this mirror passes an illumination beam but does not pass a selected fluorescent radiation component coming from the specimen.
2. The microscope according to claim 1 , wherein and said mirror for reflecting light can be swiveled out of a microscope beam path and a photomultiplier can be swiveled in its place for transmitted-light detection.
3. The microscope according to claim 1 , wherein:
at least one of the objectives is connected with adjusting devices for displacement in axial and/or radial direction and the adjustment is carried out depending on the observation beam path with respect to its intensity or contrast; and
wherein the adjusting devices are coupled with drive elements.
4. The microscope according to claim 3 , wherein said drive elements are piezomechanical drive elements.
