Claims
- 1. An eye viewing device comprising:
an imaging axis; an aperture stop disposed about said imaging axis; and an illumination system generating illumination lighting rays converging at an apex, wherein said illumination system includes an objective lens shaping illumination light rays, wherein said imaging axis intersects said objective lens, and wherein said aperture stop is disposed substantially conjugate to said apex.
- 2. The device of claim 1, wherein said aperture stop is disposed substantially coaxial relative to said imaging axis.
- 3. The device of claim 1, wherein said aperture stop is disposed in a position so that said aperture stop is in a position that is substantially conjugate to a pupil of said eye when said illumination system projects substantially a maximum amount of light through a pupil of said eye.
- 4. The device of claim 1, wherein said objective lens is adapted to converge said light rays.
- 5. The device of claim 1, wherein said imaging axis is unfolded.
- 6. An eye viewing device having a patient end and an observer end, said device comprising:
a housing; an illumination system generating illumination light rays for illuminating a structure of an eye, said illumination system comprising an objective lens and a light source; an imaging system having an imaging axis intersecting said objective lens; and an aperture stop disposed about said imaging axis, wherein said objective lens and said light source are disposed in said housing.
- 7. The device of claim 6, wherein said aperture stop is disposed substantially coaxially relative to said imaging axis.
- 8. The device of claim 6, wherein said aperture stop is sized to substantially correspond to a size of a pupil.
- 9. The device of claim 6, wherein said illumination system generates converging light converging in an apex.
- 10. The device of claim 6, wherein said illumination system generates converging light converging in an apex, and wherein said aperture stop is disposed substantially conjugate to said apex.
- 11. The device of claim 6, wherein sad imaging axis is unfolded.
- 12. The device of claim 6, wherein said aperture stop is disposed in a position so that said aperture stop is in a position that is substantially conjugate to a pupil of said eye when said illumination system projects substantially a maximum amount of light through a pupil of said eye.
- 13. The device of claim 6, wherein said device comprises optics disposed in said housing for developing a noninverted image of an eye structure.
- 14. An eye viewing device for viewing an eye having a pupil, said device having a patient end and an observer end, said device comprising:
an illumination system generating illumination light rays for illumination a structure of an eye, said illumination system comprising an objective lens, an imaging system having an imaging axis intersecting said objective lens; and an aperture stop disposed about said imaging axis, wherein said aperture stop is positioned in said device relative to said illumination system so that said aperture stop is substantially conjugate to said pupil when said device is in an operative opposition in relation to said eye.
- 15. The device of claim 14, wherein said aperture stop is disposed substantially coaxially relative to said imaging axis.
- 16. The device of claim 14, wherein said aperture stop is sized to substantially correspond to a size of a pupil.
- 17. The device of claim 14, wherein said illumination system generates converging light converging in an apex.
- 18. The device of claim 14, wherein said illumination system generates converging light converging in an apex, and wherein said aperture stop is disposed substantially conjugate to said apex.
- 19. The device of claim 14, wherein said imaging axis is unfolded.
