Laser systems

Lasers have found a very wide area of applications and laser systems are offered in hundreds  of different types. Inframet manufactures equipment for testing several types of laser systems: laser range finders, laser designators, laser pointers/illuminators, laser receivers (laser communication receivers, laser seekers, laser trackers), thermal infrared lasers and high energy lasers (HELs).

Laser range finder LRF is a measuring  device  that uses a laser beam to measure the distance to a target; typically using  time of flight principle. Laser designators are high power pulsed lasers used to designate  target  of interest to be detected by a machine system.  Laser pointer/illuminator is a device that uses laser beam to indicate/illuminate target of interest to be detected by humans. Laser receivers are devices that work as receiver blocks of laser seekers,  laser communication systems or laser trackers having a task to detect a target emitting pulsed laser light.  Thermal infrared lasers are lasers operating in long wavelength spectral range (thermal infrared) from about 2 μm to 15 μm. High Energy Lasers are lasers that emit high power CW laser beam for use in both industrial and defense applications. 

Inframet offers a long series of stations optimized for testing different groups of laser systems:
a)Laser ranger finders/designators: LUNI, LTE,  LTF, LAS,  LJT120 , LATRA, LIS, LMOB, LBOR, LBAND, LDIR
b) Laser pointers/illuminators/dazlers: LIP, L411, LDIR
c) Laser receivers/seekers: L64,
d) Thermal infrared lasers: LTIR,

e)High Energy Lasers: LAHEL.
