OptiDock™ phone scope adapter
How OptiDock holds your phone to the eyepiece
Fits many eyepiece sizes
Spotting scope today, binocular tomorrow? The clamp closes on eyepieces from 35mm to 60mm in diameter, so a single adapter can move between the optics you already own.
X, Y and Z alignment knobs
A phone lens that sits off-center shows a small circle ringed by dark edges. Three knobs move the phone along each axis, so you can center the camera over the eyepiece by hand.
Tension-lock metal frame
Holding a phone by hand over an eyepiece is awkward in a breeze. The tension-lock system and metal frame hold the phone firmly against the clamp while you shoot photos or video.
Case-on phone mounting
Pulling a case off at the trailhead is a chore. The holder is made to take most phones with their cases on, and you can remove an unusually thick case if alignment needs it.

Holding a phone against an eyepiece by hand tends to give a shaky shot with dark edges. A phone scope adapter clamps the phone in place, so the camera stays lined up with the lens.
OptiDock clamps onto eyepieces from 35mm to 60mm. One unit can serve as a spotting scope phone adapter in the field, a telescope phone adapter, a binocular phone adapter, or a microscope phone adapter for a kids' school project. Three X, Y, and Z knobs move the phone until the camera is centered on the eyepiece.
- Holds most phones with the case on.
- A rugged metal frame and tension-lock hold the phone rigid for photos and handheld video.
- Rides in a pack for hiking and field use.
Once the tension-lock is set, the phone can come off and go back on without redoing the alignment. This phone scope adapter also sits on a shelf at home between trips.
