Dual Beam IR Acousto-Optic Modulator, 9.4µm or 10.6µm

Manufacturer's part number :


Manufacturer Isomet


Description :

The DBM1186-G54-9 acousto-optic is a 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. This model is optimized for pulsed laser applications. DBM1172-G41-9 dual beam IR acousto-optic modulator is water cooling with <4% of optical insertion loss.
