The intention of this essay is to present a physical illustration of Heisenberg's Uncertainty Principle in the context of transmitted light microscopy. The practical aspects of the example herein are common knowledge to microscopists. The theoretical background using Heisenberg indeterminacy relationships...

Operation Principle of Confocal Microscopy In a conventional optical microscope, a quite high lateral image resolution (well below 1 μm) can be achieved by using a microscope objective with short focal length and a high numerical aperture. A remaining problem, however, is that light from differen...
Who discovered refraction of light? What is a reflected ray of light? What was the contribution of Robert Hooke to the microscope? What did Robert Hooke do in 1665? What type of microscope did Robert Hooke invent? What did Robert Hooke and Anton van Leeuwenhoek discover?
Light pathways in a widefield microscope. ibidi Solutions: The ibidi Polymer Coverslip and the ibidi Glass Coverslip provide ideal optical conditions for fluorescence microscopy. Widefield fluorescence is possible without restrictions when using any of the ibidi labware that contains the ibidi Polymer Cov...
When light passes through cells, small phase shifts occur, which are invisible to the human eye. In a phase contrast microscope, these phase shifts are converted into changes in amplitude, which can be observed as differences in image contrast. However, this label-free technique is strongly ...
The optical lens assembly isplaced in the bottom position of the optical mouse, from Figure 5 can clearlysee that the optical lens component is composed of a light microscope and acircular lens. The mirror will be responsible for the transmission of lightemitted from the light emitting diode li...
a beam of electrons moving at low energy to focus and scan specimens.The development of electron microscopes was due to the inefficiency of the wavelength of light microscopes. electron microscopes have very short wavelengths in comparison to the light microscope which enables better resolution power....
AFM microscopes are among the best solutions for measuring the nanoscale surface metrology and material properties of samples. A conventional compound light microscope is limited to a maximum sample magnification of approximately 1000x; a quantity that is dictated by the wavelengths of visible light. Th...
infinite light path between the objectives and the tube lens without disturbing the focus position of the objectives and the tube lens. all techniques in reflected and transmitted light can be used on one microscope with so-called “Universal optics” ...
