FLI Atlas Focuser

Today’s sophisticated imaging systems include colour 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 Atlas Digital Focuser is up to the task; an engineering pièce de résistance with unique solutions to achieving critical focus with heavy loads.

Mechanical Design Highlights
• High TPI precision adjustment screws translate into high positional accuracy
• Miniature stepper motor driven by micro-stepping controller
• Adjustment screws supported by high-load-rated bearings extend operational
life in the most demanding conditions
• Linear bearings provide torsional rigidity
• Symmetrical distribution of redundant mechanical components guarantees
consistent performance in any orientation
• Included FLI Zero Tilt Adapter ensures that system performance is not compromised by tilt, movement, or shifting
• All mechanical components are enclosed and protected from the environment
• Hidden drive motor (fully enclosed inside of Atlas Digital Focuser)
