Hi,
The electronic focus adjustment didn't seem to work in our miniscope recently. We have replaced the rigid flex PCB with a new one, but still everything looks good except the EWL. When we replaced the PCB, we noticed that there was an air bubble within the EWL lens. We were wondering if this could be an issue? Or even the cause of the EWL failure?
Thanks!
