    My 60x objective seems to have come loose. We cannot focus our nanoparticles on that objective anymore. Is there a quick fix for screwing it back in?

    Also, occasionally when we open ENVI, we receive an error message that the camera cannot be found even though it is clearly on. Suggestions?

    The objective simply screws on and off. If it is loose, turn it counter-clockwise (while on the microscope) to tighten it snugly by hand.

    On the camera error, this can occur if you leave the computer and camera on for extended periods without rebooting the computer. Of course, if the power cable or USB cable to the PCO camera are loose this will cause the error as well.
