chopping frequencies
- Low phase jitter
- Single and dual
beam experiments
- Sum and
difference reference outputs
- Bolt clamp or
rod mounting
The SR540 chopper will handle all
your optical chopping requirements - from simple experiments to dual beam and intermodulation measurements. The SR540 has a voltage
control input, four-digit frequency display, ten-turn 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.
