Spinning disk confocal

In conventional widefield optical microscopy the specimen is bathed in the light used to excite fluorophores.  The fluorescence emitted by the specimen outside the focal plane of the objective interferes with the resolution of in focus features.  As the sample increases in thickness, the ability to capture fine detail above out-of-focus signal becomes increasingly challenging. The confocal principle rejects out-of-focus light through the use of a pinhole, with the added benefit of an improvement in lateral and axial resolution.


Nikon TIRF

Various mechanisms are often employed in fluorescence microscopy applications to restrict the excitation and detection of fluorophores to a thin region of the specimen. Elimination of background fluorescence from outside the focal plane can dramatically improve the signal-to-noise ratio, and consequently, the spatial resolution of the features or events of interest.

Total internal reflection fluorescence microscopy (TIRFM) exploits the unique properties of an induced evanescent wave or field in a limited specimen region immediately adjacent to the interface between two media having different refractive indices. In practice, the most commonly utilized interface in the application of TIRFM is the contact area between a specimen and a glass coverslip or tissue culture container.
