Polymicro Technologies, a subsidiary of Molex Incorporated, 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. Polymicro’s 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 FBPI fibre is available in a range of densities and can be produced in core diameters from 50-600 μm.
##IMAGE_1_R##“Optimised for panoramic spectroscopy and sensor analysis our new broad spectrum FBPI fibre represents an industry first,” states Robert Dauphinais, business development manager, Polymicro Technologies. “FBPI fibre delivers superior performance coupled with resistance to radiation and exposure that can lead to fibre degradation and shorten product life.”
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 fibre handles both UV and NIR in a broader spectrum of wavelengths than any other optical fibre on the market today. This is particularly advantageous in expanding the spectroscopic measurement range and sensitivity of a device,” adds Dauphinais.
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.
