Abstract
A simple method for the manufacture of disposable, cylindrical, diffusing fibre tips is described. The method is suitable for plastic clad silica fibres with core diameters in the range 200–600μm. Light diffusing tips up to 40 mm in length have been constructed. The method is highly reproducible, construction is typically less than five minutes and the financial cost is negligible. The diffusers are highly efficient, delivering an amount of light at least equal to that transmitted by a plane cut fibre of the same core diameter. The uniformity of light emission along the diffuser can be modified to meet the requirements of any given treatment. The diffusers have been successfully used in interstitial photodynamic therapy.
