(January 19th, 2009) Orlando, FL. LightPath Technologies, Inc. (Nasdaq: LPTH - News),

LightPath Technologies is pleased to introduce an f/1.0, 10.6 mm focal length Long Wave
Infrared (LWIR) lens assembly designed for uncooled infrared sensors. These lenses are
designed as the primary optics for thermal imagers in a wide variety of applications including
homeland security, firefighting, predictive maintenance and driver’s vision enhancement systems in automobiles. These thermal imaging markets have a combined current estimated value of over $2.5 billion.

This new lens assembly integrates LightPath’s Black DiamondTM molded chalcogenide infrared
lenses that are a lower cost substitute for high volume diamond-turned Germanium and Zinc
Selenide optics. The unique material properties of Black Diamond glasses provide natural
athermalization for temperature stability from 25oC to 75 oC without adding additional cost. This specific design gives a 52 degree field-of-view and when paired with a 10 mm sensor with a 25 micron pixel pitch.

“LightPath Technologies is expanding its product line for Molded Infrared Optics with the
introduction of this lens assembly. This new product will continues to address the rapidly
expanding thermal imaging and night vision enhancement markets. ” said Jim Gaynor, CEO and
President of LightPath.

LightPath Technologies Inc. will be exhibiting their new Infrared Lens Assembly at the Photonics West Conference at the Moscone Center in San Francisco, California from January 26th through January 28th. LightPath’s Booth is 2128 in the South Hall.
