USB Device Driver

(applicable to Axsun Laser Engine, Ethernet/PCIe DAQ, and Camera Link DAQ)
There are no separate downloads for the USB device driver. Device drivers are installed automatically during the installation of OCT Host & AxsunOCTControl on Windows OS, or manually using Zadig.exe during the installation of AxsunOCTControl_LW on Windows OS. AxsunOCTControl_LW on Linux OS uses the usbfs kernel driver which is included in the distribution.

Sample OCT Data

Axsun OCT image data files (*.dat) are created by the AxsunOCTCapture library using the axSaveFile() command or the corresponding button in the Image Capture Tool. These files can only be interpreted by the AxsunOCTCapture library via the axLoadFile() command or the corresponding button in the Image Capture Tool. These sample data files are NOT intended to demonstrate any particular level of OCT image quality, but are available in a range of data types to aid the developer in software installation and API integration efforts.

Device Firmware & FPGA Bitstreams

(applicable to Axsun Laser Engine, Ethernet/PCIe DAQ, and Camera Link DAQ)
Please contact us for more information on updating your device's firmware or FPGA bitstream. Depending on the current firmware version, a device may need to be requalified or have some non-volatile settings reconfigured after an upgrade. We will help ensure compatibility with your preferred library versions and other device firmware prior to sending binaries or scheduling a remote upgrade and re-qualification via screen sharing.
