12. Use in fluorescence
This section refers exclusively to the use of the reflected light fluorescence microscope.
For transmitted light operations, refer to this manual in sections 8-9-10 from page 17 to page 24.

12.1 Assembling procedure (all models)

1. Insert the round dovetail socket of the illuminator
① into the hole in the microscope body and
tighten the locking screw ②. (Fig. 36).
2. Install the observation head as already explained
at page 15.
ONLY FOR B-383FL
• Disconnect all electrical cables before installing or replacing the bulb.
• The bulb has an anode and a cathode of different sizes. Respect the polarity during assembly,
respecting the bulb dimensions.
• Do not touch the bulb with bare hands to leave no traces of grease on the bulb. If this happens,
clean the bulb with a soft cloth before turning on the lamp.
• The bulb has an average life of about 200-250 hours: a time counter and a voltage indicator are
shown on the bulb power supply. Replace the bulb when the hour count exceeds 250 or if the
voltage drops below 4.5A.
• During use, the bulb, the lamp housing and the surrounding environment become hot.
• Before replacing the bulb, switch off the power supply, disconnect all cables and wait for the bulb
and the lamp housing to cool.
• After switching on the bulb, wait at least 10-15 minutes before switching it off.
• After switching off the bulb, wait for 5-10 minutes before switching it on again so that the mercury
vapors have time to condense.
• The bulb contains ultraviolet radiation that could be harmful to eyes and skin.
