A new optics with phase advances mx = 131 ° and my = 90 ° in the arc cells has been proposed for LEP. This note summarises the main results from the optics evaluation procedure that is now routinely applied to new LEP optics. This includes the study of the orbits, optics and dynamic apertures of an ensemble of imperfect machines with corrections similar to those applied in operation. It provide...

We are very pleased to introduce the inaugural issue of Biomedical Optics Express. Published by The Optical Society, Biomedical Optics Express is a new peer-reviewed journal focusing on biomedical optics and biophotonics. Biomedical Optics Express is intended to become OSA’s principal outlet for serving the biomedical optics community with rapid, open-access publication of biomedical content. A...

Zigzag ZnS thin films prepared by thermal evaporation method using glancing angle deposition (GLAD) technique. ZnS films with zigzag structure were produced at deposition angles of 0˚, 60˚ and 80˚ at room temperature on glass substrates. Surface morphology of the films w:as char:acterized by using field emission scanning electron microscopy (FESEM). The optical properties of the specimens were i...

In this paper, the physical optics method is used to study the problem of electromagnetic scattering from Haack series nose cone. First, a meshing scheme is introduced which approximates the curvature of the surface by piecewise linear functions in both axial and rotational directions. This results in planar quadrilateral patches and enables efficient determination of the illuminated region and...

Surface fouling and undesired adhesion are nearly ubiquitous problems in the medical field, complicating everything from surgeries to routine daily care of patients. Recently, the concept of immobilized liquid (IL) interfaces has been gaining attention as a highly versatile new approach to antifouling, with a wide variety of promising applications in medicine. Here, we review the general concep...

Many optical systems, such as imaging systems or laser communication systems, suffer performance degradation due to distortions in the optical wave-front. An optical wave propagates through an optically inhomogeneous medium such as the atmosphere, differences in the index of refraction along the propagation path cause variations in the speed of light propagation, which lead to phase distortions...

Doubly curved crystal X-ray optics provide intense focused monochromatic beams from laboratory X-ray tube sources. These optics are employed in crystallography and X-ray fluorescence systems and may find application to imaging. It is increasingly important to understand how optic defects impact performance for these systems. A simulation model was developed to assess the effects of misalignment...
