Imaging & Analysis Lasers
What are Imaging and Analysis Lasers?
Imaging & Analysis Lasers refer to advanced laser systems (typically pulsed) used in the research and biophotonics markets for various applications. These lasers are specifically designed for precise imaging and analysis techniques, enabling researchers to study and understand complex biological processes. They offer capabilities for fluorescence lifetime imaging, Matrix-Assisted Laser Desorption/Ionization Time-of-Flight (MALDI-ToF) mass spectrometry, and particle image velocimetry (PIV), among others. By providing tailored laser sources and specific parameters suitable for each application, imaging & analysis lasers facilitate high-resolution imaging, biomolecular analysis, and fluid flow measurements. These lasers play a crucial role in advancing research in areas such as biology, medicine, and fluid dynamics, contributing to scientific discoveries and advancements in various fields.
Imaging & Analysis Applications
Fluorescence Lifetime Lasers: Fluorescence lifetime imaging microscopy (FLIM) is a method used for measuring the time a molecule spends in the excited state. Typical lifetimes are on the order of a few picoseconds to hundreds of nanoseconds depending on the molecule, therefore ultra-short pulses in the picosecond or femtosecond range are required from fluorescence lifetime lasers.
Maldi-ToF Lasers: Maldi ToF is a method used in mass spectrometry for measuring the time it takes for ionized particles of different masses to drift to the detector. For this process to work, there must be a mechanism in place to ionize the particles (e.g., photoionization). This technique traditionally uses high pulse energy q-switched ultraviolet lasers (typically ns or ps pulsed, UV, green, or IR microchip lasers), because the photon energy must be greater than the ionization energy of the particle.
Particle Image Velocimetry Lasers: Particle Image Velocimetry (PIV) is an experimental method used for determining the velocity of a flowing fluid by monitoring the particles in the stream which are illuminated by a laser. For this application to work, particle image velocimetry lasers and cameras must be time-gated and triggered at the same time so that each image can be precisely mapped to a point in time. Typically, 532nm pulsed DPSS lasers are utilized, but any pulsed visible laser should work.
