EOSS 250TC/250TC-S

The Axsys EOSS 250TC is a premier long-range surveillance and security solution for mobile and stationary land, air, and sea related operations.

The EOSS thermal imager will detect man-sized targets at ranges in excess of 4km making it one of the most comprehensive imaging systems available today. The EOSS 250TC is widely deployed throughout the world protecting ground troops in forward operating bases through programs such as TASS, C-RAM, and FPS-2, and securing borders and protecting critical infrastructure.

The EOSS 250TC is a tri-field-of-view (17, 60, and 250mm) imaging system and is available with an advanced cooled sensor in a 320 x 256, 30µm pitch focal plane array or optional 640 x 512, 15µm pitch focal plan array for maximum resolution (EOSS 250TC-S). The EOSS 250TC has an integrated visible camera with 26x optical zoom and is mounted on a 360° precision Axsys APS 50 pan and tilt system. The camera also has an optional laser rangefinder and laser illuminator/pointer. The integrated joystick controller operates the system with push button interaction.
