The Moment is a true global shutter CMOS camera with an ultra-compact form factor, powered through USB 3.2 Gen 2. Fluorescent dyes will absorb low wavelength light and become excited as a result they will release a high wavelength light. High content imaging is primarily concerned with the automated analysis of large cell populations where the goal is to process as many cells as possible in the fastest time with the highest resolution. Confocal microscopy uses optical sectioning to take multiple, thin, 2-dimensional slices of a sample to construct a 3-dimensional model from them.

It is even possible, using advanced optogenetic methods, to optically interrogate cells to discover more about their function. Namely, to image biological samples for much longer under physiologically relevant conditions than with conventional microscopy techniques and to image samples of considerable size in a more reasonable and relevant time frame. Fluorescence is the molecular absorption of light energy at one wavelength and its nearly instantaneous re- emission at another, usually longer, wavelength. Single-molecule fluorescence microscopy represents a subset of fluorescence microscopy that uses fluorescent tags to detect and analyze individual single molecules. It is particularly used to study samples that are complex and cannot be examined under conventional transmitted-light microscope. The power of X-ray fluorescence itself is generally well acknowledged—fast non-destructive elemental analysis (typically for sodium 11 Na to uranium 92 U) suitable for accurate quantitative characterisation in both % and parts per million (ppm) regimes. Total internal reflection fluorescence microscopy (TIRF) makes use of specific optics to produce illumination light only at the 50-100 nm range at the interface of the slide, massively reducing out of focus light and improving the ability to detect fluorescent molecules. A fluorescence microscope is an optical microscope that uses fluorescence instead of, or in addition to, scattering, reflection, and attenuation or absorption, to study the properties of organic or inorganic substances. Fluorescence microscopy: a concise guide to current imaging methods. A fluorescence microscope is used to study organic and inorganic samples.
