Fiber optic solutions for power lasers

Many industrial applications require a high-power laser source. This is the case for laser welding, soldering, cutting or stripping. The power patch cords are special optical fibers, designed to carry high levels of optical energy, and thus allow the laser source to be remote. The fiber is reinforced with a specific buffer and dedicated connectors.

Fiber optic solutions for diagnosis and analysis

Fiber optics are ideal to perform fluorescence spectroscopy analysis for diagnostic applications. They allow to illuminate a target at a defined wavelength, and to collect the fluorescence emitted by the target as a reaction to the excitation caused by the incoming light. The emitted fluorescence is relevant of the composition of the target, which allows to identify the nature of the target. These properties are for instance used to practice in-vivo diagnosis of cancers using special fiber needles, and to do blood analysis in laboratory to detect diseases.
