Turn off the power of Loupe module first. Rotate the lens off and mount on the lens you need. Then turn on the power again. Users do not have to detach the Loupe modules to do so.

Yes. You can remove the barrels while really need more working distance; please follow the steps below then carefully remove the barrels:

Users can remove both the barrels and the diffusers off from G series lenses. To remove the barrels, users just rotate the barrels anti-clockwisely and the barrels will come off. To disassemble the diffusers, please use the screw driver we provide for each G series and unfasten the two screws from the diffusers. Please carefully follow the instructions to prevent any malfunction or damage.

Rotate the lens barrels clockwisely and carefully to remove the barrels. Users might need to check the focusing of lenses after mounting the barrels back because the working distance may vary. To solve this, users can take A series to focus on a flat subject again and rotate the barrels slightly tighter or looser to adjust the proper working distance.
