Optical fibre for spectroscopic analysis
17 April 2013
Interconnection
Polymicro Technologies, a subsidiary of Molex, has successfully developed a broad spectrum optical fibre with a low -OH pure silica core that demonstrates significantly reduced content of UV defects and other UV absorption centres.
The proprietary FBPI fibre takes advantage of the benefits and mitigates the limitations of standard optical fibres. Featuring improved transmission properties over a much wider spectral range, the silica-based, broadband fibre is available in a range of densities and can be produced in core diameters from 50–600 m.
In the near-infrared (NIR) wavelength region to beyond 2100 nm, Polymicro FBPI fibre attenuation is equivalent to standard NIR fibres having a low -OH silica core and F-doped cladding. Comparable to solarisation properties of standard UV optimised high -OH fibres with high radiation resistance, FBPI fibre features ultra-violet (UV) transmission down to 200 nm.
Many spectroscopic applications require high-performance optical fibres that transmit light over a broad spectrum and demonstrate minimal focal ratio degradation. Unlike standard optical fibres, which are limited by transmission spectral range, Polymicro FBPI optical fibre transmits a wider range of wavelengths with relative uniformity across the wavelength range.
FBPI broadband optical fibre is designed for a range of high performance spectroscopy applications, including optical fibre testing, environmental monitoring, gas phase measurements, precision surgical and industrial lasers and high-performance gas or liquid chromatography.
