LAB 1 - SIMPLE DIFFRACTION, FOURIER OPTICS AND ACOUSTO
... This will badly blur the image of the laser beam on the pinhole and allow some laser light to get through the pinhole when the spatial filter is placed in the optical setup. Place the spatial filter on a base, and put it in the path of the laser beam with the back (iris side) facing the laser. Adju ...

... nm, which is considerably less than that of visible light (380-760 nm). Consequently, two neighbor electron beams of such energy interfere when they are at a much shorter distance from each other. Therefore, the electron microscope can reach a resolution of about 0.2 nm, which is about 1000 times gr ...

Strategies for the compensation of specimen
... The main advantage of the confocal microscope lies in its ability to image efficiently only those regions of an object which lie close to the focal plane. This optical sectioning ability permits through-focus series of optical slices to be recorded, which can then be processed to render the volume o ...
