Based on the acoustooptical effect the dual frequency shifter DFD 40/80 allows you to move the frequency of laser light for some 10 megahertz in to separate channels. It consists of a driver electronics and two modulator elements. While frequency and amplitude of both output channels can be adjusted separately, they are phase-locked. This makes the DFD an ideal tool for heterodyne experiments.

- Complete system with driver electronics and modulators (depending on application)
- Quartz stable oscillator
- HF-safety circuit to avoid overload damage
- Microprocessor control
