Specialist optical fibre for deep-UV applications offers improved specification and durability

September 17, 2013 // By Graham Prophet
Polymicro Technologies, a subsidiary of Molex, has announced improvements to its FDP optical fibre. The latest enhancements improve solarisation of the fibre in deep UV (ultra-violet) applications (190 – 325 nm), which results in longer product life

For applications in the deep UV region, the effects of high levels of UV radiation typically cause fibre and transmission deterioration. Fibres typically lose transmission after several hours. Polymicro silica core optical FDP fibre features ultra-high UV transmission and ultra-low UV solarisation, with superior radiation resistance. Operating down to 190 nm with excellent deep UV solarisation resistance characteristics, the new FDP fibre delivers greater solarisation resistance to sustain transmission longer, while minimising damage to the fibre.

Improved FDP fibre offers approximate 10 percent more light output after initial degradation compared with the previous version, the company says; this provides better light emission and longer product life.”
