High-NA Multimode Optical Fiber Series for UV-Vis-NIR Transmission

Description

The Optical Fiber Series includes high-performance multimode optical fibers designed for laser delivery, spectroscopy, sensing, biomedical instrumentation, and industrial photonics applications requiring reliable light transmission across UV, visible, and near-infrared wavelengths.

Available in multiple core diameters, numerical apertures, and coating configurations, these multimode fibers support efficient optical coupling, high-power laser transmission, and broadband light delivery for scientific and industrial systems. The fibers are suitable for integration into spectroscopy platforms, laser processing equipment, medical devices, optical sensors, machine vision systems, and analytical instrumentation.

Engineered for low-loss optical transmission and flexible system integration, the multimode optical fiber series supports demanding applications ranging from precision measurement and semiconductor inspection to laser machining and biomedical imaging.

What Is the Difference Between Multimode and Single-Mode Optical Fibers?

Multimode optical fibers have larger core diameters than single-mode fibers, allowing multiple propagation modes of light to travel through the fiber simultaneously. This makes multimode fibers easier to couple with light sources such as LEDs, broadband lamps, and many industrial lasers.

Compared to single-mode fibers, multimode fibers are typically used for shorter transmission distances but provide advantages in alignment tolerance, light collection efficiency, and high-power optical delivery. They are widely used in spectroscopy, sensing, biomedical systems, and industrial laser applications.
