Software, drivers, manuals and service documents for FLI cameras and accessories. Start with the guide below, then jump to your product.

Windows 11 notice: The current FLI Software Installation Kit (CCD cameras, filter wheels, focusers) uses a USB driver that does not install reliably on Windows 11. A signed Windows 11 driver is in development. Until it is released, we recommend staying on Windows 10 for these devices. Kepler cameras are supported on Windows 10 and 11 (64-bit). Need help? Email sales@flicamera.com.

Which file do I need?

Kepler (CMOS) camera: install FLI Pilot V1.2.95 (Windows 10 or 11, 64-bit). Using a fiber (QSFP) link? Also install the PCIe QSFP driver. Using a CFW filter wheel with Kepler? Also install the FLI Software Installation Kit.
MicroLine, ProLine or Hyperion (CCD), CFW or CenterLine filter wheel: install the FLI Software Installation Kit, 64-bit (32-bit only for older PCs). Remove older versions first.
Using MaxIm DL, TheSkyX, ASCOM, INDI or LabVIEW? Install the driver above first, then see Third-party software.
Writing your own code? Kepler: Kepler Windows SDK 2.1.4 or Linux packages. All other FLI devices: FLI SDK 1.104.
