Replacing the deuterium lamp
The deuterium lamp for the background corrector has a limited lifetime. After a
prolonged period of operation the lamp will exhibit decreasing radiant intensity
and will ultimately fail.
The lifetime of the deuterium lamp will be prolonged if you do not switch it on
and off frequently.
You can replace the deuterium lamp assembly yourself. The replacement lamp is
fitted in a prealigned mount.
