640 TL/TD/TV THERMAL IMAGER

The 640 TL/TD/TV Thermal Imager is a handheld or weapon-mountable thermal observation device built around a 640×480 resolution uncooled vanadium oxide microbolometer detector. The 640-pixel core delivers noticeably finer target detail compared to 384 or 320-series sensors, making it practical for identifying personnel, vehicles, and equipment at extended ranges where lower-resolution units lose clarity.

The TL, TD, and TV designations typically differentiate the optical configuration — lens focal length and field of view vary across the series, with TL variants commonly offering longer focal lengths for detection ranges extending beyond 1,800 metres on a standing human target, while TD and TV configurations provide wider fields of view suited to area scanning and close-to-medium range observation. Thermal sensitivity (NETD) on 640-class detectors generally falls at or below 40mK, allowing detection of low-contrast heat signatures in cluttered backgrounds.

Operating features typically include multiple colour palettes — white hot, black hot, and pseudo-colour modes — digital zoom up to 4x or 8x, image and video capture to internal memory or microSD, and a display output option for remote viewing. Battery life on standard CR123 or rechargeable 18650 cells typically runs between 4 and 8 hours depending on operational settings.

In Pakistan, 640-series thermal imagers are used by security forces, border surveillance units, and private protection teams operating in low-light and zero-visibility conditions across varied terrain.

Tactical Supply Pakistan stocks the 640 TL/TD/TV Thermal Imager series for professional observation and targeting applications.
