Abstract
A system for determining refractive eye aberrations includes an optical arrangement having a first conjugate lens having an effective focal length (EFL) of about 150 millimeters and a second conjugate lens having an EFL of about 88.9 millimeters. The first and second conjugate lens are each positioned in a housing along a return light path and are separated by a distance of about 238.9 millimeters. The arrangement enables a range of measurable diopters of an eye to be between about −10 diopters to about +10 diopters.
