The facility includes silica preform manufacture via Extrusion, Stacking (in a dedicated HEPA filtered room), and Ultrasonic milling and drilling. In addition there is a glass working lathe with a hydrogen burner for preform preparation.Ìý

Additional equipment available within the IPAS glass fibre manufacturing facilities for the characterisation of both soft and silica glass, preforms and fibres include specialised microscopes including a SNOM/AFM.

The SNOM/AFM part can run in collection or transmission mode, and is equipped with an IR detector and an in-built red laser. This equipment is available for both fibre characterisation and other applications.

Surface functionalization takes a material whose surface chemistry is dictated by that material's surface composition and surface properties, and attaches to it specific chemical functional groups, or biochemical functionalities, to impart tailored physical, chemical, or biochemical properties to that material's surface. For example, a material’s optical properties can be changed, or the introduction of specific functional groups to react in controlled ways with molecules in fluids. It can also include the introduction of receptors for adding chemical or biochemical specificity to a sensor surface. Bulk glass, planar wave guides and fibre surfaces can be functionalised, both internally and externally, allowing the production for example, of novel optical based fibre sensors.

The powerful combination of capabilities available at IPAS, coupled to its competence for synthetic and surface chemistry in the functionalisation of glass fibres, places IPAS in a unique position to offer its surface functionalisation know-how and facilities, to create new fibre-based platform technologies to underpin paradigm-changing tools for human health, the environment, industrial processes and defence systems.

As part of the OptoFab node of the ANFF, IPAS offers a variety of commercial services from the supply of custom glasses and fibres to theoretical modelling and development of novel sensor platforms. Academic groups and companies are encouraged to contact IPAS with their specific requirements or to access our specialised equipment and services.
