It will be housed in Monash University's upcoming Melbourne Centre for Nanofabrication (MCN), which will pay 1.5 million Euros (AUD$2.5m) for the machine and an additional estimated $30,000 per year for related utilities. In EBL, a beam of electrons is scanned across a film. The beam etches a desired pattern onto the film, which can then be transferred onto other materials.
Scientists and engineers from across the nation are expected to use the EBL tool for developing new banknote fraud prevention technologies, microtexturing surfaces, and manufacturing x-ray optical elements. One example of EBL-related anti-counterfeit technology is Exelgram, which was developed by CSIRO in the 1990s and has been used in Hungrarian, Estonian and New Zealand bank notes, Ukranian visas and American Express travellers' cheques.
Although they appear similar to holograms, Exelgrams are more sophisticated. Their effect cannot be achieved using industrially available optical devices.
Exelgrams use EBL to create arrays of mirrors that are tens of microns wide. The mirrors are arranged on a material's surface and reflect light to form images that change as the material moves....read more>>>...
