Polymicro extends specialty optical fibre offering

Polymicro Technologies, a subsidiary of Molex Incorporated, has extended its Specialty Optical Fibre offering with the introduction of FBPI optical fibre and Hollow Silica Wavelength fibre products which has been optimised for near infrared (NIR) attenuation and ultraviolet (UV) solarisation resistance to improve transmission over a wider spectral range. The silica-based FBPI optical fibre is also able to deliver industry-first panoramic spectroscopy and sensor analysis.

Available in a range of core diameters from 50-600µm, broad spectrum FBPI optical fibre with a low -OH pure silica core is able to demonstrate significantly reduced content of UV defects and other UV absorption centres. 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 UV transmission down to 200 nm.

“Many spectroscopic applications require high performance optical fibres that transmit light over a broad spectrum,” states Robert Dauphinais, business development manager, Polymicro Technologies. “Unlike standard optical fibres, which are limited by transmission spectral range, Polymicro’s proprietary optical fibre transmits a wider range of wavelengths with relative uniformity across the wavelength range.”

Strong and flexible Polymicro Hollow Silica Wavelength (HSW) fibre for CO2 laser delivery can be optimised for wavelengths in the infrared (IR) region from 3-20µm for a range of applications, including replacement for high cost, heavy, rigid articulated arms in medical and dental laser applications, industrial cutting, and laser printing and marking. Enabling high laser power delivery =100W, the hollow construction silica simplifies end termination, reduces abrasion and provides a robust buffer in harsh environments. The geometry of the biocompatible fibre can be easily changed to accommodate part customisation.
