German optical electronics group Jenoptik on Wednesday posted a jump in preliminary revenue for the full year, which was supported by the performance of its advanced photonic solutions division.

For the full year, the company posted adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) of around €210 million ($226 million), higher than last year's €184.1
