Agiltron Inc., a manufacturer of fiber optic and infrared imagers and detection products, has announced that it has expanded its detector offerings by acquiring privately held SensArray Infrared for an undisclosed amount. SensArray, of Burlington, makes IR detectors for spectroscopic and analytical applications. It has made standard and customized lead selenide (PbSe) and lead sulfide (PbS) infrared detectors and infrared arrays for more than 20 years. Agiltron, whose home base is north of Boston, makes optical switches, variable optical attenuators, high-power optical components, optical polarization and time controls, and molded infrared lenses. It has about 100 employees. Besides its optical product operation, Agiltron has two new subsidiaries: Thermaltron, for microelectromechanical systems-based sensors, and Nanotron, for new materials-based products. Agiltron said the acquisition allows the company to expand its offering of IR detector products to the 1- to 5.5-µm range. It will continue to support all current SensArray products, Agiltron said.
