DBM1199-G54(51)-9C
Dual Beam IR Acousto-Optic Modulator
The DBM1199 series is an alternative to the popular DBM1186 series. The M1199 differs in that the coolant is not in direct contact with the Germanium block. These Dual Beam Modulators incorporate a novel acoustic beam steering technique to allow the user to switch between the +1 and -1 Bragg orientations. Under electronic control, the user can generate two sequential output beams from a single laser input. Independent modulation levels can be applied to the A and B first order outputs.
