Using the fluorescence
Assembling the epi-fluorescence attachment
Take the attachment out of its packaging and put it onto the microscope stand, then tighten the attachment lock-
ing screw.
Place the optical head onto the top of the attachment and tighten the optical head locking screw. Connect the
cable from the epi-fluorescence attachment to the output jack on the rear of the microscope.
Lighting up the fluorescence LED light
Connect the external 6Vdc power supply to a wall socket, and plug its output to the jack on the rear of the mi-
croscope:
MAIN SWITCH
In order to light up the epi-fluorescence LED, press the main switch on the rear in position II. Then rotate the
brightness adjustment knob on the left to the desired value. Pull the filter selector (1) to right or left in order to
insert the fluorescence filter into the optical path. Put the filter selector (1) in the center if you want to use the
brightfield transmitted illumination. Unlike a mercury lamp system, B-383LD LED illumination doesn't need any
power-up time for heating, and can be used immediately after switching on. Also, the LED source is pre-aligned
in factory and doesn't need any alignment operation.
Looking at the fluorescent specimen
Focus on your sample, and adjust the light intensity as needed through the brightness adjustment knob. In order
to improve the darkness of the background (thus improving contrast), it is strongly suggested to put the provided
black plate under the stage):
