Two-lens telecentric model eyes for image distortion measurement in adaptive optics ophthalmoscopes.

ABSTRACT: Here we present the design of telecentric model eyes for measuring image distortion in adaptive optics ophthalmoscopes, using pairs of achromatic or near-achromatic commercial off-the-shelf (COTS) and/or custom doublet lenses. The proposed model eyes can operate over visible or visible plus near infrared wavelength ranges, across a 15-diopter focus range, with an 8 mm entrance pupil diameter. COTS lens selection was implemented as a systematic evaluation of catalog lenses after optimization of axial distances. Custom lens optimization was initially guided by wavefront aberration constraints derived from object-shift 3^rd order aberration theory, before traditional variation of surfaces and distances to minimize a performance metric. When a wavefront corrector compensates for fiel
