Semrock Inc., a unit of Idex Corp., recently shipped its millionth hard-coated optical filter, the company announced Wednesday. Founded in 2000, the company began applying its hard coating filter technology to the biotechnology and optical instrumentation in 2004. Since then, its three optical filter platforms — fluorescence instrumentation and microscopy, Raman spectroscopy instrumentation and laser-based analytical instrumentation — have seen significant growth, the company said. “In the company’s early years, few of us dared to imagine we’d ship over a million of our hard-coated, high-performance optical filters,” said General Manager Robert Beeson. Semrock is focusing its efforts now on the imminent completion of a new high-volume production cell so it can ship the next million filters in less time than it took to ship the first million, Beeson said.
