Optical aberrations in a spinning pipe gas lens.
If a heated pipe is rotated about its axis, a density gradient is formed which results in the pipe acting as a graded index lens. In this study we revisit the concept of a spinning pipe gas lens and for the first time analyse both the wave propagation of optical fields through the lens, and determine the optical aberrations introduced by the lens to the laser beam. We show that such lenses are ...
متن کاملNegative index lens aberrations.
We examine the Seidel aberrations of thin spherical lenses composed of media with refractive index not restricted to be positive. We find that consideration of this expanded parameter space allows for the reduction or elimination of more aberrations than is possible with only positive index media. In particular, we find that spherical lenses possessing real aplanatic focal points are possible o...
متن کاملLens Aberrations and Ray Tracing
When beam quality is a concern in an optical setup, lens aberrations are an undesired side-effect. Which aberration affects a particular experiment is not always as obvious as one would like. Take for example, the simple goal to concentrate the maximum amount of optical power at a certain point using a lens. The first “obvious” requirement is that the initial beam should be well collimated, sen...
متن کاملOptical aberrations, accommodation, and visual acuity with a bioanalogic continuous focus intraocular lens after cataract surgery
Purpose To evaluate the visual outcomes, pseudoaccommodation, and wavefront aberrometry after implantation of Wichterle IOL-Continuous Focus (WIOL-CF®, Gelmed International, Kamenne Zehrovice, Czech Republic) by i-Trace aberrometry. Methods In this retrospective interventional case series study, after cataract surgery with implantation of accommodative WIOL-CF®, the patients were evaluated wi...
