This unit
The Horiba PTI OC-4000 Optical Controller provides precise synchronization and phase control of optical choppers and detectors in spectroscopy systems. This unit delivers selectable disk configurations - 5-sector and 30-sector - enabling operation across wide frequency and exposure time ranges. The OC-4000 combines analog external control, TTL synchronization outputs, and phase adjustment capability to support lock-in detection and time-resolved measurements in fluorescence and absorption spectroscopy.
Technical Specifications Frequency Range
5-Sector Disk: 5 Hz to 667 Hz
30-Sector Disk: 30 Hz to 4000 Hz Exposure Time
5-Sector Disk: 750 µs to 100 ms
30-Sector Disk: 125 µs to 17 ms Phase Jitter
5-Sector: 3.0% at 5 Hz, 1.5% at 10 Hz, 0.36% above 20 Hz
30-Sector: 0.18% at 25 Hz, 0.12% at 50 Hz, 0.06% above 100 Hz Linearity: ±0.5% Accuracy: ±0.5% of least significant digit across entire range Phase Control Range: 0 to 180 degrees External Control Input: 0 to 4 VDC TTL Output: 5 Volt standard
Key Features
LED frequency readout for direct monitoring
Wide-range speed control knob for chopper frequency adjustment
Precise phase adjuster for optical signal alignment relative to chopper blade position
Switchable disk configurations (5-sector and 30-sector) for application-specific frequency requirements
RJ-12 connector for chopper drive control
BNC connectors for synchronization and reference signals
Typical Applications The OC-4000 serves lock-in detection systems, time-correlated single-photon counting experiments, and modulated light source synchronization in fluorescence spectroscopy. Its dual-disk design accommodates both low-frequency chopping and high-speed modulation requirements in research and analytical laboratories.
Compatibility & Integration Standard 5 Volt TTL output interfaces directly with lock-in amplifiers, signal averagers, oscilloscopes, and computer data acquisition systems. External control via 0–4 VDC input allows speed regulation from remote equipment. RJ-12 connectivity integrates with PTI fluorescence systems. BNC signal outputs enable straightforward synchronization with detection and analysis instruments.
