Optical Chopper
Newport - New FocusRequest Info
SANTA CLARA, Calif., Oct. 23, 2014 —
With a chopping frequency phase-locked to its own internal frequency synthesizer, the Model 3502 optical chopper from New Focus can chop from 4 HZ to 10.65 kHz.
The chopper features outputs at the sum and difference of the inner and outer wheel’s chopping frequencies for nonlinear-optics experiments, as well a high-stability phase shifter than can lock two choppers together for long fluorescence-decay measurements.
Replacing the 3501 chopper, Model 3502 can achieve variable duty-cycle chopping by mounting two of the same wheels on the chopper head.
