A beta-ray spectrometer for coincidence measurements
An intermediate image beta-ray spectrometer has been constructed utilizing the focusing properties of a Ushaped magnetic field distribution. The construction and performance of the instrument are discussed. A transmission of ten percent has been attained with a resolution of about six percent. A scintillation spectrometer is used in conjunction with the intermediate image spectrometer for the p...
متن کاملIn vitro strehl ratios with spherical, aberration-free, average, and customized spherical aberration-correcting intraocular lenses.
PURPOSE To determine in vitro image qualities of artificial eyes achieved with spherical, aberration-free, average spherical aberration-correcting, and customized spherical aberration-correcting IOLs in centered, decentered, and tilted positions. METHODS The in vitro performance of these IOL models was determined by optical bench measurements. The experimental setup included a laser light sou...
متن کاملSpherical Aberration, Accommodation and Myopia
Myopia should not be considered a benign condition because of the potential risks of vision loss associated not only with high myopia but also with the procedures used to correct myopia. Results from animal studies demonstrating that emmetropization is an active rather than a passive process and the induction of myopic refractive errors with imposed hyperopic defocus underlie the hypothesis tha...
متن کاملSpherical Aberration of Intraocular Lenses
Advancements in cataract surgery and intraocular lens (IOL) design have optimized the postoperative optical performance of the pseudophakic eye. One of the recent spotlights of IOL design has been formulating optical properties similar to a clear, young lens and addressing spherical aberration. Spherical aberration in the human eye is a combination of the positive spherical aberration of the co...
متن کاملAdaptive optics simulation of intraocular lenses with modified spherical aberration.
PURPOSE Adaptive optics systems can be used to investigate the potential visual benefit associated with correcting ocular wave-front aberration. In this study, adaptive optics techniques were used to evaluate the potential advantages and disadvantages associated with intraocular lenses (IOLs) with modified spherical aberration profiles. METHODS An adaptive optics vision simulator was construc...
