A microscope illumination device includes at least one light source and a light conversion element. The light conversion element is configured as at least one optical waveguide which contains different fluorescent materials each having different emission ranges. The at least one light source is arranged...
The spatial distribution and spectrum of the light reaching the sample has been characterized, and is described in detail. 展开 关键词: Engineering Optics Materials Science A System for In Situ UV-Visible Illumination of Transmission Electron Microscope Samples ARIZONA STATE UNIVERSITY Peter Crozier ...
If the modulation grating is projected through the microscope condenser onto the object, then kg=km is indeed the largest shift which can be projected since it uses the whole NA of the optical system (Figure 16.4A). But if the grating can be put in contact with the object, then there ...
To break the optical diffraction limit, SIM modulates the high-frequency information of the sample, which is originally beyond the cutoff frequency of the optical transfer function (OTF), into the microscope passband by structured illumination, usually in the form of three-step phase-shifting fringe...
The Leitz filter-cube system was so efficient that even today similar types of filter cubes are still used by most microscope manufacturers for multi-wavelength fluorescence microscopy. This development finally led to the development of automated multi-wavelength fluorescence epi-illuminators accommodating ...
While it is tempting to adjust the intensity on these light sources with the rheostat, a better solution is the use of neutral density filters, often installed in the base of the microscope. For simpler systems or for a variable effect, place two polarizing filters covering the light port. ...
