Molecular Manipulation & Analysis Applications

Confocal Fluorescence Microscopy Lasers: Confocal microscopy is an optical technique that allows for extremely high spatial resolution imaging by placing two conjunct pinholes in the optical path. Most of the visible wavelengths can be used in confocal fluorescence microscopy, but it’s essential that all confocal fluorescence microscopy lasers (typically CW, low noise, single-mode, visible) have a high quality TEM00 beam profile.

DNA Sequencing Lasers: DNA sequencing or genome sequencing is an extremely powerful tool that allows the identification of the four basic DNA molecules adenine (A), cytosine (C), guanine (G), and thymine (T) by tagging them with fluorescence reporter molecules. Like all fluorescence applications, most of the visible wavelengths can be used in DNA sequencing, but it’s essential that all DNA sequencing lasers (typically CW, low noise, single-mode, visible) have a high quality TEM00 beam profile.

Flow Cytometry Lasers: Flow cytometry is a laser-based technology employed in cell counting, cell sorting, biomarker detection, and protein engineering. This technology is used to analyze the physical and chemical characteristics of particles in a fluid as it passes through at least one laser. Flow cytometry lasers (typically CW, low noise, single-mode, visible or IR) provide a high-quality TEM₀₀ beam profile, low noise, and high pointing stability and power stability.

Optogenetics Lasers: Optogenetics is a biological technique that uses light to control cells in living tissue, typically neurons. While very little optical power is needed, optogenetics lasers (typically ns ps or fs pulsed, visible) are still the preferred delivery method because of their ability to be focused and targeted to specific areas of the brain. Additionally, several wavelengths in the near-infrared region allow optogenetics lasers to be transmitted through bone and tissue eliminating the need for opening the skull.
