Edite and Gustavo,

you are right about the assumption of condensation. It happens if humidity enters the sealed camera head (if you have an actively cooled cameras). Although it should not, this sometimes happens and the best advice is to contact the manufacturer and ask for a repair. Usually the humid air has to be removed and the head has to be refilled with dry gas (if there was no vacuum in there before) and if there are any humidity scavengers in the camera head, they will have to be re-activated.

Good luck and all the best,
Gerhard

Dear Edite,

We had the same issue in exactly the same camera: about 1 month ago in our case the camera had been functional for around 4 years. I wondered whether this could be just from the age of the camera, but was still surprised to see this defect.

Regardless of warranty aspects, in your situation I would still contact Andor to look for a solution together, it should not be that difficult to have the sealing remade.

Good luck and all the best,
Gustavo

Dear All,

I wonder if anybody in the list had the same/similar issue we have in the lab.

We have water condensation on the camera sensor (Andor Zyla camera) when we turn on. It disappears when we turn off the camera.
The camera is attached to a lens as shown here:

This is how it looks in the image:

Do you have suggestions on how to fix this?

Thank you for your help!
Best wishes,
Edite
