 TWO DIMENSIONAL ACOUSTO-OPTIC DEFLECTORS
Russian Technological Association™ presents a wide range of Two Dimensional Acousto–Optic Deflectors (2-D AOD) in which two AO crystals are mounted orthogonally to provide X-Y capability. All 2-D AOD units can produce a change in first order spot position in X-Y directions and simultaneously a change in intensity of laser beam in response to a change in the frequency and amplitude of the input RF signal.
The special construction of all units allows to get the confined directions between input beam and beam deflected by AOD. The 2-D AO Deflectors can operate with CW as well as with Pulsed lasers with average power from microwatts till several watts and hold a very high density of laser radiation.
Warranted life time of all units is more than 10 000 hours. Most of RTA Deflectors are unique and can defy competition with world known manufacturers.
RTA produced 2-D AOD are completely computer controlled devices with high speed programmable deflection of the laser beams. All models of 2-D AOD have high operational flexibility and can be easily integrated as core elements into different scanning systems. The OEM products are available on request.
