The VALOI easy Precision Framing Helicoid is made for both VALOI easy systems (easy35 and easy120), offering 20mm of step-less adjustment to allow for more precise framing. The helicoid screws onto the distance tubes that come with the easy35 and easy120. Add it between your lens and the tubes, adjust, lock, and start scanning.
The Precision Framing Helicoid gives you lots of flexibility with up to 20mm of smooth, step-less adjustment. Once you have achieved the desired framing, two thumb screws let you lock the helicoid in place, ensuring your frame stays in focus.
When used vertically, a heavy camera and lens might still move the helicoid. Please test with your own equipment before using it in a vertical position.
