The mounting structure of the lens 优质文献 相似文献The mounting and detaching structure and lens hood of lens case and lens barrel sum PROBLEM TO BE SOLVED: To provide a lens hood and lens barrel attachment/detachment mechanism that can stably obtain a click feeling.SOLUTION: A lens barrel.....
An unusual form of the retina and inhomogeneity of the lens in Lymnaea has been demonstrated by light and electron microscope studies. There are dorsal and ventral pits and comb-like hills between them in the retina. The density of the spherical lens is suggested to decrease from the center ...

To correct for the distortions in the imaging optics, a physical grid was inserted at the back focal plane of the objective lens. b, A cut in the kx–ky plane in the presence of the grid as imaged by the detector before correction. Overlaid on top is a yellow box representing a ...
Co-assembly of different connexin isoforms produces channels with unique properties and enables communication across cell types. Here we used single-particle cryo-electron microscopy to investigate the structural basis of connexin co-assembly in native lens gap junction channels composed of connexin 46 ...
The researchers found that unlike human eyes that work with lenses, the shrimp's eyes contain a series of nanometer-sized mirrors arrayed in a concave formation that functions like a lens. The reflective material coats the light detectors in the shrimp eye's retina. These detectors, highly sens...
PROBLEM TO BE SOLVED: To provide a lens mounting structure of rimless spectacles which is capable of more surely fixing and holding lenses, has excellent safety and does not hinder the cleaning of lens surfaces and a method for mounting the same.吉田 武彦...
The crystal structure of bovine lens IIIb-crystallin at 2.5 resolution previously reported was interpreted using a consensus sequence derived from related vertebrate sequences on the assumption that IIIb-crystallin derived from the C-crystallin gene. It has recently been shown that IIIb is a product ...
Lens-shaped structures within thermocline potentially play a significant role in subsurface transport of mass, heat, and salt in the global ocean. Whilst such structures have been documented in many oceanic regions, none has been observed in the China Seas. This study reports on observations of a...
