Carl Zeiss Vision would not confirm or deny a report that it may go public soon. The company, shared between the Carl Zeiss group and the EQT fund, saw its sales grow by 9 percent to €447 million in the first half of its financial year, ended last March 31, and the growth rate was in the double digits on a currency-neutral basis. The Zeiss group raised its total sales by 11 percent to €1,451 million, and its operating profit (EBIT) rose by 28 percent to €242 million. Officials of CZV say the company is enjoying strong demand for its new iScription technology, which has been adopted by some 600 opticians, mostly in German-speaking countries. The company has delivered twice as many systems as planned and could have sold an equal number, but it wants to ensure the proper levels of service and training for this new way of dispensing glasses.
