Abstract
An ophthalmological imaging apparatus includes a main body portion, an internal power source and an external power source. The main body portion has a light source producing light for imaging the eye to be examined. The internal power source is provided in the main body portion and supplies electrical energy to the light source for the production of the light. The external power source is provided discretely from the main body portion and supplies from outside of the main body portion electrical energy to the light source corresponding to the deficiency in the amount of light from the light source produced by the electrical energy from the internal power source relative to a desired amount of light for imaging.
Claims15
An ophthalmological imaging apparatus comprising:
- a main body portion for effecting the imaging of an eye to be examined, said main body portion having a light source producing light for the imaging of the eye to be examined;
- power source means provided in said main body portion, said power source means supplying electrical energy for the production of light to said light source;
- and
- connecting means, provided in said main body portion, for connecting thereto an external power source apparatus for supplying from the outside of said main body portion electrical energy to said light source corresponding to the deficiency in the amount of light from said light source produced by the electrical energy from said power source means relative to a desired amount of light for imaging.
An ophthalmological imaging apparatus comprising:
- a main body portion for effecting imaging of an eye to be examined, said main body portion having a light source producing light for the imaging of the eye to be examined;
- power source means provided in said main body portion, said power source means supplying electrical energy for the production of light to said light source;
- and
- external power source means provided discretely from said main body portion, said external power source means supplying from the outside of said main body portion electrical energy to said light source corresponding to the deficiency in the amount of light from said light source produced by the electrical energy from said power source means relative to a desired amount of light for imaging.
An external power source apparatus for use with an ophthalmological imaging apparatus including a light source producing light for the imaging of an eye to be examined, and power source means for supplying electrical energy for the production of light to said light source, said external power source being connected to the ophthalmological imaging apparatus for executing the imaging of the eye to be examined, said external power source apparatus comprising:
- a connecting portion for connection to the ophthalmological imaging apparatus;
- and
- external power source means for storing electrical energy corresponding to the deficiency in the amount of light for said light source produced by the electrical energy from said power source means relative to a desired light amount for imaging and for supplying to said light source of the ophthalmological imaging apparatus the stored electrical energy through said connecting portion so that the stored electrical energy is supplied to said light source with the energy from said power source means.
