Specimen protection in transmitted-light applications
In the Stemi DV4 / DR, thermally sensitive specimens are automatically protected from excessive heat
from the transmitted-light illuminator.
The automatic system arranges for the transmitted light intensity to be reduced after expiry of 3 minutes
to a level which is uncritical for constant operation (60%), provided that maximum illumination intensity
has been set for the transmitted-light mode.
If the illumination intensity for transmitted light has been set to 100 %, the blue LED lights up.
Of course, the transmitted-light illumination intensity can be reset to full lamp performance any time.
