studied in terms of a thickness parameter defined as \\(\\left[ {\\frac{m}{s}} ight]D = \\frac{{{d_1} + {d_2}}}{{{d_1} - {d_2}}}\\) , where d 1 and d 2 are the distances of the first and second surfaces of a thick lens from that of an Equivalent Thin Lens....

The lens of the LED lighting plays a vital role in affecting the quality of the lighting itself. Up to now, a thick lens known as a cup-shaped lens was commonly used as the part of the lens needed for the complex operations of the light. Although the cup-shaped lens was excellent ...
hydrochemical processes have been studied in thick BGH lenses because of their influence on drinking-water quality. Stuyfzand (1993) investigated the hydrochemistry of dune and adjacent areas, where mixing of saline and freshwater is an ongoing, although...
Plus, it comes with an elastic knit closure and polyester lens that gives me a snug fit and everlasting comfort. I appreciate that it is also water and wind-resistant, thanks to its suede leather coat. Top that with an insulated sponge with just the right thickness of 2mm to maintain brea...
Over almost five decades of development and improvement, Magnetic Resonance Imaging (MRI) has become a rich and powerful, non-invasive technique in medical imaging, yet not reaching its physical limits. Technical and physiological restrictions constrain
1b, c. The SEM image highlights the very regular lamination sequence of the Gr/PMMA laminate, and proves the uniform graphene distribution, with ~250 nm-thick layer of PMMA separated by the CVD graphene sheet. Raman spectroscopy has been adopted for the quality control of graphene during ...
A fish-eye compound lens or another type of multilayer lens is typically used for wide-angle imaging. While researchers have attempted to develop wide-angle cameras using metalenses in the past, they have had poor image quality or other problems. The researchers employed a variety of metalenses ...
The specimens included CUBIC2-optically cleared whole murine ovaries, thick murine brain sections, ethyl cinnamate (ECi)-cleared murine kidney sections and native (non-cleared) human pancreas organoids (Fig. 2). Individual whole murine ovaries expressing GFP-c-kit were stained with DAPI, cleared ...
Pump and probe beams were synchronized by a delay line and focused on the sample by a lens with a focal length of 500 mm and a spherical mirror with 200 mm focal length, respectively, assuring that the pump spot size was larger than the probe spot size. The pump beam was blocked ...
