Zoom Lens with Aspherical Lens for Camcorder
International Lens Design, 1990Recent optical systems consist of spherical lens elements, because the spherical lens is suited for productin and the surface inspection. But now as the precision production and mass production technologies are developed, there are many lens systems with aspherical lens elements for still camera and projection TV.

Crystal formation in the lens in both the young and the aged has been reported by various observers from time to time. The morphology and the chemical nature of the crystals are also of varied nature; for example, Goulden12and other observers have described crystalline opacities in the lens showing green and blue iridescence in morbid conditions such ...

Recent reports implicating anticholinesterase agents in the production of lens opacities have led us to look for the target of these agents, that is, the enzyme cholinesterase, in the lens. A form of cholinesterase, sensitive to low concentrations of eserine, has been found.

THE "MYODISC" LENS AND BIFOCAL LENS
Archives of Ophthalmology, 1934Most ophthalmologists have been confronted with the complaints of extremely myopic patients who object to the wearing of heavy ugly lenses. There has always been a need for a light and finer appearing lens to meet the needs of these patients. During the past year I have used over one hundred pairs of a new type of lens for high myopia in corrections ...

Abstract This chapter presents variants of Brunswik’s lens model aimed to understand whether, when, and why trait judgments are more or less accurate. After outlining the basic concepts of lens models, it describes exemplary studies that have applied the lens model to unravel personality expression and impression formation processes that

The human lens grows by a process of epithelial cell division at its equator and the formation of generations of differentiated fibre cells. Despite the process of continuous remodelling necessary to achieve growth within a closed system, the lens can retain a high level of light transmission throughout the lifetime of the individual, with the ability ...

AbstractParalemmin was identified in the chicken lens as a protein with mol. wt 65 kDa and a splice variant of 60 kDa, both soluble in Triton X‐100. Paralemmin is localized to the plasma membrane of fiber cells, and was not detected in the annular pad cells. Thus in the chick lens it is another feature of fiber cell differentiation. Its localization to
