Optical Chopper
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...
