  • Publication number: 20240049964
    Abstract: An ophthalmic examination apparatus comprises an alignment light generator, which directs beams of light from separate locations toward an image of an aperture stop of an imaging unit of the ophthalmic examination apparatus, and causes an envelope of the beams of light to converge to and diverge from a waist, which is within an alignment range of the ophthalmic examination apparatus. An eye is at an examination location with respect to the imaging unit when the waist of the envelope is located at least partly inside a pupil of the eye. The examination location of the ophthalmic examination apparatus is within the alignment range. The imaging unit receives reflections of the beams of light from a cornea of the eye within the alignment range, the eye being similar to a standard eye within standard tolerances.
