Microscope and lamphouse

1. A microscope comprising:

an excitation light source which emits an excitation light in an ultraviolet wavelength range;

a phosphor which receives the excitation light and emits illumination light in a specific wavelength range;

a microscope body which includes an illuminating unit including a collector lens collecting the illumination light and illuminating a specimen by the illumination light, and which includes an internal power source for supplying power to at least a portion of the illuminating unit and to the excitation light source, wherein the internal power source is switchable to supply power to a halogen lamp and to the excitation light source;

an observation unit for observing the specimen illuminated by the illuminating unit; and

a lamphouse that is detachably mountable to the microscope body, and that includes a lamp supporting member for replaceably supporting the excitation light source, which is adapted to be electrically connected thereto,

wherein:

one of the microscope body and the lamphouse comprises a transformer for transforming the power supplied from the internal power source into power suitable for the excitation light source when the excitation light source is connected to the lamp supporting member,

the illuminating unit includes an excitation-light cut filter that shields the excitation light after passing the phosphor,

the illuminating unit includes a light-source supporting adapter which supports the excitation light source, and includes the lamp supporting member on which the light-source supporting adapter is mounted, wherein the light-source supporting adapter is replaceable at least with the halogen lamp,

the light-source supporting adapter positions the phosphor at a focal position of the collector lens when mounted on the lamp supporting member,

the phosphor is replaceably located at the focal position of the collector lens when the lamphouse is mounted to a mounting part of the microscope body, the phosphor being located inside the microscope body,

the illuminating unit images a conjugate image of the phosphor, and

the conjugate image of the phosphor has an image size that is the same as an image size of a filament of the halogen lamp.
