Patent ID: 7286286

Claim:
A stereo microscope comprising: a base which is formed of a first portion having a sample mounting surface on which a sample is laid and a second portion formed to be higher than the height of the sample mounting surface; a support disposed between the first portion and second portion of the base; an arm section elevatably disposed with respect to the support; a stereo microscope main body detachably attached to the arm section to obtain an observation image of the sample; a focusing mechanism which moves up/down the arm section with respect to the support; a first illuminating section including a light source in which a plurality of light emitting diodes emitting light fluxes are disposed on a plane to transilluminate the sample; a second illuminating section which includes a light source in which a plurality of light emitting diodes emitting light fluxes are disposed on a plane, and which is detachably attached to either one of the arm section and an end of the stereo microscope; a power substrate which supplies power to the first and second illuminating sections, respectively; a glass plate which is disposed on the first portion of the base and on which the sample is laid; and a dimmer which is provided on the second portion, and adjusts the amount of light of the first and second illuminating section; wherein the first portion is provided so that the sample mounting surface is disposed on a plane of the same height as the height of the glass plate, the second portion houses the power substrate and is formed to be higher than the height of the sample mounting surface, and the dimmer is provided behind the support and on an upper surface of the second portion which is formed higher than the sample mounting surface.
