Null Ronchi-Hartmann test for a lens.

چکیده
A method to design Ronchi-Hartmann screens for improved alignment in the testing of fast plano-convex spherical lenses is presented. We design null screens that produce aligned straight fringes for observed patterns. The designs of these null screens are based on knowledge of the caustic by refraction. A qualitative test for a lens is presented.

Application of the Ronchi test to intraocular lenses: A comparison of theoretical and measured results.
We studied the spherical aberration of an intraocular lens, using third-order theory, ray tracing, and bench measurements by the Ronchi test. Good agreement was obtained for these three methods of investigation. In particular we found that the Ronchi test is an accurate method for quantifying this aberration.

متن کاملWavefront Measurement for Long Focal Large Aperture Lens Based on Talbot Effect of Ronchi Grating
We propose a wavefront measurement method based on Talbot effect. It is well known that the wavefront of large aperture long focal lens is difficult to be measured. Here a new method for wavefront measurement of large aperture long focal lens is presented, which is accomplished by fitting the slope of sub-wavefront in the whole aperture while the sub-wavefront slope is got by calculating the sh...
متن کاملMeasurement of wave-front aberration in soft contact lenses by use of a Shack-Hartmann wave-front sensor.
Lower- and higher-order wave-front aberrations of soft contact lenses were accurately measured with a Shack-Hartmann wave-front sensor. The soft contact lenses were placed in a wet cell filled with lens solution to prevent surface deformation and desiccation during measurements. Aberration measurements of conventional toric and multifocal soft contact lenses and a customized soft contact lens h...
متن کاملA new test for optical surfaces
For an optical system to produce the best possible images, the optical surfaces of the mirrors and lenses must be polished to the correct shape to within a fraction of the wavelength of light (in most cases, this means a few tens of nanometers). Interferometry is usually used to inspect the mirror or lens and ensure that the correct shape has been achieved. However, the equipment is expensive a...
