Versaperm Vapour Permeability measurement

Enhancing an optical fibre’s properties

Enhancing an optical fibre’s properties

Optical fibres are highly prone to vapour permeability problems, especially for underground, underwater or sensor-based applications.  Not only is the strength of polymer coated fibres dependant on permeability, but also the spectral shift response of optical whispering-gallery modes is due to the adsorption and desorption of water molecules.  Versaperm’s specialist measurement equipment can make a huge difference.

Versapem’s latest systems measure the vapour permeability of fibre products and their casings both quickly and with an accuracy well into the Parts Per Million (PPM) range – in some applications it can reach PPB accuracies.   This becomes critically important as even the manufacturing processes can easily affect a material’s vapour permeability by a factor of four times. Published permeability values do not take this into account.

The system can optionally determine vapour permeability not just for water vapour but for virtually every gas – including in exotic environments as well as in acidic or hydrocarbon-based conditions.  It can also control a wide range of physical conditions from temperature (-80 C to over +1000 C ), pressure, and partial pressure / humidity. 

The equipment can measure both the vapour permeability of a product’s outer case and the optic fibre itself.

As well as designing, manufacturing and supplying the equipment to laboratories, including standards laboratories around the world, Versaperm additionally offers both laboratory testing and consultancy services.
