Proven Technology
Derived from Thales’ proprietary MELT (Miniature
Eyesafe Laser Transceiver) technology, CELT2
uses Erbium glass laser technology engineered to
meet stringent military and environmental safety
performance standards. CELT2 uses a single-shot,
time of flight measurement principle that is capable
of ranging to static or fast-moving platforms.
Technical Data
The CELT2 is ideally suited for end-users requiring
installations to externally mounted platforms. It
offers a true plug and play compatibility within a
host of military-based environments without any
measured loss in performance.

CELT2 features an extensive BIT facility and use
monitoring system. It can also communicate range,
status and diagnostic data to a host management
system and can operate effectively from a LAV
compatibile MIL-STD-1275B Power Supply.
Applications
CELT2 can be mounted directly onto AFV, LAV, MTB
platforms, as part of Electro-Optic payload fitted to
weapon systems or a host of other land, naval and
air based applications.
