Similar to the graphene, BP is a layered material with basic cells of honeycomb structure in which the different layers are stacked together with the aid of weak van der Walls forces61. Different from the other 2D materials mentioned above, BP has a unique direct band-gap which is layer ...
The counter-rotating wedges can be aligned such that the combined optical beam passing through it can be steered along a substantially linear axis. In another embodiment, a beam steering module, for example242, can be configured as a plano-concave lens in combination with a plano-convex lens....
lens (Edmund Optics, Adjustable ReflX Objective 36X/0.5NA IR FIN) to the sample. Transmitted light from the sample was collected and collimated by a 3-in focal length plano-convex ZnSe lens and refocused by another identical lens on a liquid nitrogen-cooled mercury–cadmium–telluride ...

Fit-free alternatives such as phasor plot are also used to retrieve the fluorescence lifetimes. In phasor analysis, the fluorescence decay in each pixel is converted into a vector and represented in a two-dimensional polar plot (phasor plot) [50]. Pixels with similar fluorescence lifetime will ...

To this end, the back panel is covered with a retro-reflective material, a similar panel is placed below the floor of the vessel and a plane mirror is positioned above the vessel. The lenses of the two cameras are equipped with small mirrors to direct the light on the same axis as the...
