The area provides a reference unit, for example in reference ranges for urine tests. [3]Used for grading of soft tissue tumors: Grading, usually on a scale of I to III, is based on the degree of differentiation, the average number of mitoses per high-power field, cellularity, pleomorphism, and an estimate of the extent of necrosis (presumably a reflection of rate of growth).
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.

The Tough TG-4 is a significant upgrade over its predecessor with the addition of Raw support. Olympus' cool 'Live Composite mode', a pair of custom setting spots on the mode dial, and additional underwater modes are also new features. [8] Olympus Tough TG-5: 12.0 2017 Olympus Tough TG-5 is the upgrade from TG-4 but with less megapixels. [9]
The first microscope manufactured at Olympus was called the Asahi. [32] Currently, Olympus is a worldwide renowned manufacturer of microscopes. Olympus offers a complete range of microscopes, which covers applications from education and routine studies up to state of the art research imaging systems, both in life science and materials science.

Epifluorescent imaging of the three components in a dividing human cancer cell. DNA is stained blue, a protein called INCENP is green, and the microtubules are red. Each fluorophore is imaged separately using a different combination of excitation and emission filters, and the images are captured sequentially using a digital CCD camera , then ...
Lower damage in cells. In aqueous systems (such as cells), medium to low repetition rates (1 – 200 kHz) allow for thermal diffusion to occur between illuminating pulses so that the damage threshold is higher than with high repetition rates (80 MHz). [8] [9] The whole object can be observed simultaneously because of the wide-field illumination.
Oil immersion objectives are used only at very large magnifications that require high resolving power. Objectives with high power magnification have short focal lengths, facilitating the use of oil. The oil is applied to the specimen (conventional microscope), and the stage is raised, immersing the objective in oil. (In inverted microscopes the ...
Endomicroscopy is a technique for obtaining histology-like images from inside the human body in real-time, [1] [2] [3] a process known as ‘optical biopsy’. [4] [5] It generally refers to fluorescence confocal microscopy, although multi-photon microscopy and optical coherence tomography have also been adapted for endoscopic use.
