The SR540 chopper will handle all your optical chopping requirements—from simple measurements to dual-beam and intermodulation experiments. The SR540 has a 4-digit frequency display, front-panel frequency control, analog voltage frequency control and two reference outputs with selectable operating modes. Two anodized aluminum blades are provided: a 5/6 slot blade for frequencies up to 400 Hz, and a 25/30 slot blade for frequencies up to 3.7 kHz. Reference outputs are provided for frequencies corresponding to each row of slots, as well as the sum and difference frequencies.
Features of SRS Stanford Research Systems SRS540 Optical Chopper Controller
Optical Chopper Applications
In this application, a single optical beam is chopped by the outer
row of slots, and the reference output from the right BNC is used
to lock the
Dual-Beam Experiment
In this arrangement, the output from a single source is split and
chopped at two different frequencies by the two rows of chopper
slots. One beam passes through the experiment while the other is
used as a reference beam. The beams are recombined and sent to the
same detector. Two
