Intraoral imaging illumination apparatus

1. An intraoral imaging and illumination apparatus comprising:

a rear portion comprising an imaging device and an illumination device;

a beam splitter disposed in the rear portion; and

a front portion removably connected to the rear portion, wherein

the front portion is formed as a light guide,

the illumination device is adapted to couple light into the front portion and towards a leading end of the front portion opposite the rear portion so as to illuminate a first object,

the imaging device is adapted to image the first object, and

the beam splitter is adapted to split light emitted by the illumination device and incident thereon into a first fraction directed towards the front portion and a second fraction directed towards a second object different from the first object.

2. The intraoral imaging and illumination apparatus of claim 1 , wherein the front portion is adapted to reflect light coupled into the front portion from the illumination device.

3. The intraoral imaging and illumination apparatus of claim 1 , wherein the rear portion defines a first longitudinal axis, wherein the imaging device or the illumination device is axially arranged with respect to the first longitudinal axis.

4. The intraoral imaging and illumination apparatus of claim 3 , wherein the imaging device or the illumination device is arranged offset with respect to the first longitudinal axis.

5. The intraoral imaging and illumination apparatus of claim 1 , wherein the second object is disposed within the rear portion.

6. The intraoral imaging and illumination apparatus of claim 5 , wherein the imaging device is adapted to image the second object.

7. The intraoral imaging and illumination apparatus of claim 1 , further comprising an automated focusing device disposed within the rear portion, wherein the automated focusing device is configured to switch focus between the first object and the second object.

8. The intraoral imaging and illumination apparatus of claim 1 , wherein the front portion comprises a proximal section facing the rear portion and a distal section facing away from the rear portion, wherein the proximal section and the distal section are angled relative to one another, wherein the front portion comprises a reflecting device disposed at a transition from the proximal section to the distal section.

9. The intraoral imaging and illumination apparatus of claim 8 , wherein the proximal section defines a second longitudinal axis, wherein the first longitudinal axis and the second longitudinal axis overlap when the front portion is connected to the rear portion.

10. The intraoral imaging and illumination apparatus of claim 9 , wherein the front portion comprises a rear end facing the rear portion, wherein a first optical interface is arranged at the rear end, wherein the first optical interface is tilted with respect to the second longitudinal axis.

11. The intraoral imaging and illumination apparatus of claim 8 , wherein the distal section defines a third longitudinal axis, wherein the third longitudinal axis is angled with respect to the second longitudinal axis, wherein a second optical interface is arranged at the leading end of the front portion, wherein the second optical interface is tilted with respect to the third longitudinal axis.

12. The intraoral imaging and illumination apparatus of claim 1 , wherein the illumination device comprises at least one LED or laser.

13. The intraoral imaging and illumination apparatus of claim 12 , further comprising at least one collimating device adapted to collimate light emitted from the at least one LED or laser.

14. The intraoral imaging and illumination apparatus of claim 12 , wherein the at least one LED or laser are tilted with respect to a central axis.

15. The intraoral imaging and illumination apparatus of claim 1 , wherein the illumination device simultaneously illuminates the first object and the second object.

16. An intraoral imaging and illumination apparatus comprising:

a rear portion comprising an imaging device and an illumination device;

a beam splitter or dichroic mirror disposed in the rear portion;

an automated focusing device disposed within the rear portion; and

a front portion removably connected to the rear portion, wherein:

the front portion is formed as a light guide,

the illumination device is adapted to emit light through the beamsplitter,

the beam splitter or dichroic mirror is adapted to split light emitted by the illumination device and incident thereon into a first fraction directed towards the front portion and a second fraction directed towards a color standard or palette of color references,

the first portion of light couples into the front portion and towards a leading end of the front portion opposite the rear portion so as to illuminate a first object,

the automated focusing device is configured to switch focus between the first object and the color standard or palette of color references, and

the imaging device is adapted to image the first object and the color standard or palette of color references, depending on the focus of the automated focusing device.
