10Camera and Technology OverviewBackgroundThe Thermal-Eye™ 250D Camera is a part of the L-3Communications Infrared Products (L-3 CIP) Thermal-Eye™product line. Thermal-Eye™ 250D is a revolutionary thermalimaging system that is the result of many years of research andexperience. L-3 CIP has long been a leader in the productionand development of night vision systems based on infraredthermal imaging. Over the years, L-3 CIP’s experience haslead to many improvements in performance and reliability ofnight vision systems. In an effort to make this technologymore affordable, L-3 CIP’s engineers and scientists developeda unique way of translating infrared energy into electronicsignals. This innovation, combined with experience indeveloping and building military night vision systems, haslead to the creation of Thermal-Eye™ 250D Camera. NowL-3CIP is providing affordable commercial thermal imagingsolutions for law enforcement, marine, security, and othercommercial uses while continuing to supply other specialproducts that meet the particular needs of the military.Customer ServiceAt L-3 Communications Infrared Products (L-3 CIP), we havemade considerable investment in training our personnel, andwe are equipping and training our dealers to help you installand apply our Thermal-Eye™ products.

Hence, ‘infrared’ (or ‘IR’)refers to that range of electromagnetic wavelengths just belowthat capable of sight by the human eye. In the IR range,energy from a scene is not sensed by sight (light) but rather bytemperature.
