Molex Subsidiary Polymicro extends Specialty Optical Fibre

“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.”

Optimised for near infrared (NIR) attenuation and ultraviolet (UV) solarisation resistance to improve transmission over a wider spectral range, Polymicro silica-based FBPI optical fibre delivers industry-first panoramic spectroscopy and sensor analysis. Available in a range of core diameters from 50-600 μm, broad spectrum FBPI optical fibre with a low -OH pure silica core demonstrates 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.

Strong and flexible Polymicro Hollow Silica Wavelength (HSW) fibre for CO₂ laser delivery can be optimised for wavelengths in the infrared (IR) region from 3-20 μm 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.  Available with custom buffers, HSW fibre features removable, reusable Poly-Lok™ connectors ideal for prototyping.
