Superlensing microscope objective lens.
Conventional microscope objective lenses are diffraction limited; they cannot resolve subdiffraction features of a size smaller than 250-300 nm under white lighting condition. New innovations are required to overcome this limitation. In this paper, we propose and demonstrate a new superlensing objective lens that possesses a resolution of 100 nm, which is a two-times resolution improvement over...
متن کاملObjective analysis of contact lens fit.
PURPOSE To assess the validity and repeatability of objective compared to subjective contact lens fit analysis. METHODS Thirty-five subjects (aged 22.0±3.0 years) wore two different soft contact lens designs. Four lens fit variables: centration, horizontal lag, post-blink movement in up-gaze and push-up recovery speed were assessed subjectively (four observers) and objectively from slit-lamp ...
متن کاملObjective analysis of toric intraocular lens rotation and centration.
PURPOSE To assess the repeatability of an objective image-analysis technique to determine intraocular lens (IOL) rotation and centration. SETTING Six European ophthalmology clinics. METHODS Eyes with an Akreos AO aspheric IOL with orientation marks were imaged. A masked observer rated image quality. The axis of rotation was determined from a line bisecting the IOL orientation marks. This wa...
متن کاملHeating by absorption in the focus of an objective lens.
We derive an integral solution for the local heating of a linearly absorbing, uniform medium exposed to strongly focused light. Numerical results for local heating under typical multiphoton microscopy and optical trapping conditions are presented for various aperture angles. In contrast with common Gaussian beam approximations, our model employs the focal-intensity distribution as described by ...
متن کاملIsotropic diffraction-limited focusing using a single objective lens.
Focusing a light beam through a lens produces an anisotropic spot elongated along the optical axis, because the light comes from only one side of the focal point. Using the time-reversal concept, we show that isotropic focusing can be realized by placing a mirror after the focal point and shaping the incident beam. This idea is applied to confocal microscopy and brings about a dramatic improvem...
