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 alaserbeam to measure thedistanceto a target; typically using time of flightprinciple. 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 directional 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.
