OCT Data Acquisition Boards

Excelitas’ Axsun Data Acquisition (DAQ) boards are purpose-built for swept-source Optical Coherence Tomography (SS-OCT) systems, delivering unmatched integration and performance. Designed to work seamlessly with Excelitas’ market-leading swept lasers, these DAQ boards eliminate the costly uncertainties of third-party digitizers, freeing your team to focus on innovation and user experience. With high-speed sampling, robust interfaces, and integrated FPGA processing, the Axsun DAQ line provides a complete solution for OCT imaging engines.

Key features

• High-speed performance: Sampling rates up to 550 MS/s with 12-bit ADC resolution for precise OCT signal capture.
• Multiple interface options: Choose from Gigabit Ethernet, PCIe, or CameraLink to suit your system architecture.
• Integrated OCT engine: Combines swept laser, k-clock generation, balanced photoreceivers, and DAQ board into one streamlined solution.
• Flexible wavelength support: Available at 1060 nm or 1310 nm with 50 kHz or 100 kHz A-line rates.
• On-board FPGA processing: Real-time OCT image processing reduces CPU load and accelerates system performance.
• Simple scanner integration: Image_sync input enables straightforward synchronization with galvanometers, MEMS scanners, or rotational probes.
• Compact and efficient: Power consumption ≤ 3 A @ 12 VDC ensures efficient operation in diverse environments.
• Developer-friendly tools: SDK includes GUI utilities and API with sample code for rapid integration.
