Newport / New Focus 3501 Optical Chopper Controller Overview
Features:
- Crystal Controlled Frequency Synthesizer
- Minimize Jitter and Drift of Chopper Head
- Harmonic and Subharmonic Chopping
- Chopping Frequency of 4 Hz to 6.4 kHz
- Harmonic Chopping from 2 to 15
- Subharmonic Chopping from 1/2 to 1/15
The New Focus Model 3501 Optical Chopper System is designed to interrupt light paths in optical experiments at frequencies from 4 Hz to 6.4 kHz. Both single and dual beam experiments can be performed across a broad range of chopping frequencies. The chopper has a crystal controlled frequency synthesizer that serves as an internal reference frequency for locking the chopper to a particular chopping frequency. Reference frequencies can also be provided through the Sync Input to allow the chopper to lock to an external source. Several measures ensure that jitter and drift of the chopping frequency is reduced to a minimum. Precision photo-etched wheels are mounted on a high quality DC motor. The motor head has a photo-sensor for monitoring the chopping frequency of the outer part of the wheel. The chopper controller then actively stabilizes the motor speed to match the desired chopping frequency. This technique minimizes phase noise at the chopping frequency and provides for long-term stable chopping with a minimum of frequency drift.
The New Focus 3501 Optical Chopper Controller may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).

Fantastic company with great people! We are lucky to have them in Champaign!
- Kamal A.
We found Artisan when our PXI Chassis broke, which shut down our production line. We were up and running in less than a day because they shipped overnight and talked our tech guys through the installation over the phone. ATG saved the day big time!
- Lonnie G.
Don’t worry about damage to your items during shipping – the box ours came in could have taken a beating and would have still survived!
