Japan's Fujikura Corporation has developed an ultra-resistant ultraviolet (UV) optical fiber
that is more resistant to long-term use than its conventional products.
UV is used for a variety of purposes, including UV exposure, lithographic semiconductor detection, and water treatment disinfection
.
In these areas, optical fibers are used as a means
of providing UV light easily and safely.
However, the long-term use of optical fibers has been a problem, especially 260 nm short-wavelength UV irradiation, because UV irradiation causes defects in quartz glass, resulting in fiber degradation
.
The Company launched ultra-UV-resistant optical fibers with the aim of expanding their use
in semiconductor-related equipment, UV sterilization lamp monitors and spectrum analyzers.
By employing special treatments to optimize the structure and improve the characteristics of the manufacturing process, the company has successfully suppressed the occurrence of defects in optical fibers, thereby greatly improving their durability
.
In addition, the new optical fibers can be used for light guides and displays in harsh radiation environments, such as in atomic reactors that suppress deterioration caused by loss
.
The company will use its own special fiber optic technology to continuously benefit society
.
For conventional optical fibers, long-term exposure or radiation of UV light causes silicon covalent bonds to break, resulting in defects (color centers).
These defects have a large band of light absorption around the 215 nm wavelength, which reduces transmission in the UV region
