Fujikura manufacture and supply a variety of high performance large core optical fibres.
Fujikura's large core optical fibre is made from silica glass, which is excellent for transmission of high density optical energy from ultraviolet rays to near infrared rays. A superior guide for laser beams; with a wide range of wavelengths for applications which require high power optical energy. For example: laser processing machinery and laser cutters, optical sensors, analyzers etc.
Terminal configuration (sleeve, connector) can be either Fujikura standard or customer specifications.
Features:
Fine Optical Permeation over a wide region (DUV ~ NIR)
Excellent performance in Laser Welding Machines and in the Laser Surgery Field where High Power Optical Energy is required
High Mechanical Strength allows easy handling
Various Terminal Assemblies are available to suit customer specific requirements
Applications:
UV Spot Curing
High Power Laser Optic Transmission
Radiation Resistance
Spectrum Analyser
Laser Surgery
Temperature Measurement
