The importance and accuracy of the human visual system have led scientists researchers to do their best study it, know its problems, how treat them. eye lens tilt is possibly due a specific accident such as blow or like. So, this manuscript was submitted tilting effect on performance determine tolerance values. Using (ZEMAX-EE) software program relying Liou Brennan model Eye (LBME), one most ac...

We describe the optimum telescope focal ratio for a two-element, three-surface, telecentric image-transfer microlens-to-fiber coupled integral field unit within constraints imposed by microoptics fabrication and optical aberrations. create generalized analytical description of parameters from first principles. find that performance, including all aberrations, design constrained an analytic mode...

The efficiency potential of a small-size solar-pumped laser is studied here. solar head was composed fused silica aspheric lens and conical pump cavity, which coupled redistributed the concentrated radiation from focal zone parabolic mirror with an effective collection area 0.293 m2 to end-side Ce (0.1 at%):Nd (1.1 at%):YAG rod 2.5 mm diameter 25 length. Optimum design parameters were found thr...

Low tracking accuracy of trackers, structure vibration by winds, and lens deformation temperature lead to non-vertical incident irradiation Fresnel lens, which necessitates a secondary concentrator in actual engineering application concentrating photovoltaic module. In this study, focusable uniform convergence microprism is added between solar cell improve efficiency focal spot energy uniformit...

Optical coherence tomography is a well-known technique for the optical imaging biological tissues. However, depth scanning range of high-resolution restricted by its focus. In this study, Zinc Selenide (ZnSe) Microlens Array (MLA) employed to overcome depth-of-focus limitation tomography. The ZnSe material with low Abbe number and high chromatic dispersion extends focus transverse resolution. M...
