TREND Networks C1000-OH Optical Chopper, Open Head, 4 - 5000 Hz, 3/30-Slot Blade, RS-232, 15 VDC

Trend Networks C1000-OH Programmable Optical Chopper (Open Head)

Precision Optical Chopping for Optical Labs and Research Applications

The Trend Networks C1000-OH is a programmable optical chopper designed for precise light modulation in laboratory, photonics, spectroscopy, and optical measurement applications. Featuring an open-head design and a standard 3/30-slot blade, the system supports operating frequencies from 4 Hz to 5000 Hz, making it suitable for a wide range of optical testing and research environments.

The C1000-OH combines crystal-controlled frequency stability with programmable operation, allowing users to accurately set and monitor chopping frequencies through the integrated controller. A bidirectional RS-232 interface enables remote control, status monitoring, and easy integration into automated test setups.

Designed with a phase-locked loop (PLL) control system, the unit can synchronize to an external clock source from 4 Hz to 5 kHz. The controller can then measure and display the frequency of the external reference, supporting applications that require precise timing and synchronization.

The compact optical chopping head connects to the controller via a 10-foot coiled cable, simplifying installation while providing flexibility for laboratory bench configurations. Its small footprint allows easy integration into compact optical systems and experimental setups.
