LightPath Technologies Adds New Mid-Wave Infrared Collimator to Its Catalog

ORLANDO, FL--(Marketwire - Apr 26, 2011) - LightPath Technologies, Inc. (NASDAQ: LPTH), a global manufacturer, distributor and integrator of patented optical components and assemblies, announced today it has added a new Mid-Wave Infrared (MWIR) fiber collimator using LightPath's molded infrared aspheres. This collimator is designed as a beam expanding optic for MWIR fibers or as a collimating lens for Quantum Cascade Lasers (QCL) used in a wide variety of applications including infrared countermeasures (IRCM), and gas analytical instrumentation for environmental sensing. These infrared markets are growing rapidly as the cost of MWIR laser sources continues to decline.

This new collimator is based on LightPath's existing MWIR collimating lenses and extends our existing product line of collimators into the infrared. These new lenses are manufactured from LightPath's Black Diamond™ chalcogenide glass and are a less expensive substitute for high-volume, diamond-turned Germanium and Zinc Selenide optics.

"LightPath Technologies is continuing to expand its product line for Infrared Optics with the introduction of these collimators. These new products are an expansion of our business in high performance molded aspheres for laser collimation. The combination of LightPath's experience in laser collimation and our new Black Diamond infrared optics is proving to be an excellent market for our unique capabilities," said Jim Gaynor, CEO and President of LightPath.
