An early stage of hyperthermia can be "heat exhaustion" (or "heat prostration" or "heat stress"), whose symptoms can include heavy sweating, rapid breathing and a fast, weak pulse. If the condition progresses to heat stroke, then hot, dry skin is typical [ 2 ] as blood vessels dilate in an attempt to increase heat loss.

Critical illumination acts to form an image of the light source on the specimen to illuminate it. [2] This image is formed by the condenser or collector lens. This illumination is bright but not always even, as any structure in the light source (for example the filament of a light bulb) will be visible in the
Solutions such as correlated cryo-fluorescence light microscopy, [19] and super-resolution light microscopy (e.g. cryo-PALM [20]) can be integrated with cryoET. In these techniques, a sample containing a fluorescently-tagged protein of interest is plunge-frozen and first imaged in a light microscope equipped with a special stage to allow the ...

Moreover, live-cell imaging often employs special optical system and detector specifications. For example, ideally the microscopes used in live-cell imaging would have high signal-to-noise ratios, fast image acquisition rates to capture time-lapse video of extracellular events, and maintaining the long-term viability of the cells.
