Product Details

  • FLI Atlas Digital Focuser

    • Achieve critical focus with heavy payloads (up to 25-pounds) with the FLI Atlas Digital Focuser!
    • High TPI precision adjustment screws translate into high positional accuracy.
    • Miniature 105,000-step motor driven by micro-stepping controller with a resolution of 150 nm per step!
    • FLI Atlas Digital Focuser includes Zero Tilt Adapter for no compromises in shift, tilt, or movement.


    Today's sophisticated imaging systems include color filter wheels (asymmetrical weight distribution), off-axis guiders, rotators, corrective optics, and CCD cameras. Together they present a formidable group of equipment that must be moved with micron accuracy and no image shift to achieve the finest results. The FLI Atlas Digital Focuser is up to the task; an engineering marvel with unique solutions to achieving critical focus with heavy loads.
