On-Trak Photonics OT301 Position Sensing Precision Amplifier

The On-Trak Photonics OT301 is a precision position-sensing amplifier designed for real-time processing of current outputs from all types of position-sensing detectors (PSDs). It provides X, Y, and Sum analog outputs with a 0.1 µA to 1.5 mA dynamic range and a bandwidth up to 15 kHz, ensuring accurate beam-position tracking independent of intensity fluctuations. Featuring four transimpedance amplifier channels, six selectable gain settings (4×10³–4×106 V/A), and adjustable Zero/Cal knobs, it offers precise calibration and offset nulling. Packaged in a compact, plug-and-play format with automatic detector biasing, the OT301 enables efficient integration for tasks like beam alignment, mirror stabilization, and nanometer-scale position sensing in photonics and motion control systems.
