Coherent Inc.Request Info
Coherent Inc. has expanded its CUBE family of solid-state CW visible diode laser modules with three new wavelengths: 488 nm (50 mW), 685 nm (40 mW) and 730 nm (30 mW). The compact laser heads measure 100 x 40 x 40 mm, making them suitable for integration into instrumentation used for life sciences, metrology and inspection applications. The models are available with Center for Devices and Radiological Health safety accessories to enable stand-alone operation in laboratory settings. Because they use direct diode technology, they offer advantages over other solid-state CW visible laser technologies, and they deliver an order of magnitude improvement in electrical efficiency and compactness over legacy ion lasers. They produce true circular output, M2 beam quality of ≤1.2 and low beam divergence.

flow cytometry
A method of measuring the characteristics of microscopic particles, usually cells, as they flow in a fluid stream through a beam of light. Particles may be stained with fluorescent dye and the fluorescence detected via laser illumination.
The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
The science of measurement, particularly of lengths and angles.
