There is disclosed a microscope constitution in which an base including an image pickup device is disposed confronting the underside of a stage portion via an optical portion having a linear optical axis, and a lighting head is assembled/disposed with respect to the stage portion so as to be rotatable/adjustable around two axes different from the optical axis via first and second arms.
1. A microscope comprising:
a stage portion on which a sample is laid;
an optical portion which faces a surface opposite to a sample laying surface of the stage portion, and which has an optical axis along which an optical image of the sample laid on the stage portion is taken;
an image pickup portion which is provided at an image forming position of the optical portion, and which converts the optical image of the sample into an electric signal; and
a lighting selecting mechanism including a plurality of position adjustment portions which variably adjust an irradiation direction of a lighting head for irradiating the sample laid on the stage portion to selectably set one of a plurality of lighting modes, including transillumination, upper deflected lighting, and lower deflected lighting.
2. The microscope according to claim 1 , wherein the plurality of position adjustment portions comprise:
a first position adjustment portion which is provided at the stage portion so as to be rotatable around a first axis to adjust the lighting head around the first axis; and
a second position adjustment portion which is connected to the first position adjustment portion so as to be rotatable around a second axis that is parallel to the first axis to adjust the lighting head around the second axis.
3. The microscope according to claim 2 , wherein the first and second position adjustment portions are connected to each other via a link mechanism so that the position adjustment portions are adapted to cooperate with each other around the first and second axes.
4. The microscope according to claim 3 , further comprising a positioning mechanism which releasably maintains the first and second position adjustment portions in adjustment positions.
5. The microscope according to claim 2 , further comprising a positioning mechanism which releasably maintains the first and second position adjustment portions in adjustment positions.
6. The microscope according to claim 2 , wherein the first axis perpendicularly intersects the optical axis of the optical portion.
7. The microscope according to claim 1 , wherein the plurality of position adjustment portions comprise:
a first position adjustment portion which is provided at the stage portion so as to be rotatable around a first axis and to adjust the lighting head around the first axis; and
a second position adjustment portion which is disposed with respect to the first position adjustment portion so as to be movable in an axial direction of a second axis that is parallel to the first axis, and so as to be rotatable around an axis perpendicular to the second axis, to adjust the lighting head in the axial direction of the second axis and around the axis perpendicular to the second axis.
8. The microscope according to claim 7 , further comprising a positioning mechanism which releasably maintains the first and second position adjustment portions in adjustment positions.
