Patent ID: 8500283

Claim:
An ophthalmic microscope-attachable aberrometer, comprising: an afocal relay defining an optical axis, a front object plane, and a back image plane, wherein said image plane is conjugated to said object plane; a Hartmann-Shack wavefront sensor positioned at said image plane and capable of measuring wavefront aberrations of a beam emerging from said object plane and propagating through said afocal relay; a folding reflector disposed between said afocal relay and said object plane; a probe beam projected along said optical axis and propagating toward said object plane; a mounting mechanism to attach said aberrometer onto said ophthalmic microscope such that said aberrometer, in its operation position, is movable with said ophthalmic microscope while said optical axis remains in alignment with an observation axis of said ophthalmic microscope; and a positioning mechanism enabling to position said optical axis to: a first position in alignment with said observation axis to perform wavefront measurement, and a second position away from alignment with said observation axis, to avoid interfering in any way with either working space or image quality of said ophthalmic microscope; wherein said positioning system enables back and forth positioning and repositioning said aberrometer at said first and second positions, and wherein said aberrometer remains attached and installed with said ophthalmic microscope.
