Spectrum Thin Films Inc., originally of Bohemia, has moved its headquarters to Hauppauge, both in New York. The new facility is 16,000 sq ft, more than twice the size of the old one, and includes a 3000-sq-ft particle-controlled cleanroom and a coating laboratory. The company said that the facility will allow it to increase its research into optical coatings and will enable it to provide better customer service.
