Dust in a diagonal mirror or diagonal prism

The dust that almost always accumulates in the diagonal mirror or prism is usually not a problem, as it sits loosely on the surface. The dirt can be easily removed with a blower. Please do not blow it out with your mouth, as some moisture will always be present!

If pollen has accumulated, the mirror must be removed and specially cleaned. Otherwise, the pollen will attack the coating.

We always remove the dust before the optical inspection.
