Aerosol Delivery System AES-02 APPLICATIONS: Aerosol delivery system AES-02 is an accessory for fabrication of optical fiber preforms, where special dopants and precursors are delivered into deposition zone by aerosol technology. This method permits either aerosol or direct particle deposition techniques (in-situ deposition) to be used in fabrication of highly doped amplifier fibers (EDFAs) or dual clad (laser) fibers. Using nebulizer, dissolved reagents are sent into deposition zone in substrate tube in the form of liquid, finely dispersed into very small droplets. DESCRIPTION: AES-02 unit is an add-on device for standard MCVD preform making system (but can be used with OVD and PCVD devices as well), which permits use of MCVD preform lathe for fabrication of standard preforms s when aerosol process is not used. It can be (on customer’ request) integrated with deposition system control software and process computer. AES-02 aerosol system consists of: ?? nebulizer assembly with aerosol generator, reagent tank with thermal bath, circulation pump and quartz sliding tube ?? s Optacore’ rotary seal for aerosol applications (RSH-03, see separate catalogues), for aerosol delivery directly into hot zone, using sliding quartz tube, moving in unison with burner carriage ?? sliding support mechanism, made of sturdy, lightweight extruded aluminum profiles and fixed to lathe headstock ?? control cabinet with power supply, front panel commands for manual operation and optional interface to deposition line control system ?? installation and start-up support by Optacore personnel ?? OPTION: mass flow controller, power supply and control electronics for carrier gas (helium gas recommended) ? ? OPTION: process support or know-how PRECURSORS & SOLVENTS: AES-02 aerosol system permits use of reagent solutions containing glass forming materials (i.e. TEOS or even silica particles), rare earth ion precursors (chelates, acetates), aluminum, germanium or phosphorous containing precursors, dissolved in water, alcohol or cyclic organic solvents.

Doping by transition elements and metal ions is also possible. By its versatility and wide choice of reagents, it provides development and research engineers with exciting possibilities to design new and improved silica glass materials and products. OPTIONS: Optacore offers AES-02 with full installation and process start-up support. Customers receive a list of most suitable solvents and precursor materials, as well as training in set-up and preform fabrication procedures as part of commissioning work. When required, process support or know-how in fabrication of specific products and use of specific processes or compositions can be offered (option). ACCESSORIES & CUSTOM DESIGN AES-02 aerosol system can be installed to a wide spectrum of preform lathes (Photonium, Heathway, SGC, Nextrom, Arnold, Litton, Lefevre and others) by modifications to rotary seal design and fixing parts for the s sliding mechanism. It can be combined with Optacore’ CDS-03 Chelate Doping system, through use of the same rotary seal assembly.
