just the microscope's focus to the protective glass surface (first fo-
cusing plane).
30. If the protective glass is dirty, perform the cleaning similar to the
cleaning procedure described under the protective conduit op-
tion.

tive glass. In doing so, ensure that no dirt is situated on the
quartz-block end-face. Do not touch the new protective glass with
your fingers. Use the white protective packaging in which the pro-
tective glass was delivered in order to screw the new protective
glass onto the fiber connector.
