Belfast-based company Andor Technology have increased their profits by 37%.
Pre-tax profit was up to £9.7m in the last financial year.
The company's chief executive Conor Walsh said that although the climate is difficult, he was confident they would be able to sustain their level of growth, by focusing on emerging markets.
Andor make high-tech scientific digital cameras for laboratory equipment.
The Belfast-based company began in Queen's University, but listed on the London stock exchange seven years ago.
"Over the last 14 years Andor has grown on average 30% per annum, so it has been a long period of strong growth numbers," said Mr Walsh.
He said the company's performance had brought access to money to fund growth, but that the directors had made a deliberate choice to try and keep profits in the local economy.
"The management of the company are from Northern Ireland, we have our roots here, we have an emotional connection with our home country," he said.
