11.1 Preparation
11.1.1 Verify that the plug from the AC mains outlet is connected firmly into the connector of the
power supply units.
11.1.2 Make sure the power cord is connected firmly.
11.1.3 When transmitted light observation is required, pull out the filter system and make the hole
in the light path.
11.1.4 Be sure to use immersion oil when using fluorescent OIL objectives.
11.1.5 When it is required to interrupt observation for a short period, use the shield in the assistant
excitation filter part.
11.1.6 Precautions on the specimen colour fading:
11.1.6.1 The system employs high-intensity excitation light to enable bight
observation of dark fluorescent specimens. As a result, if high-power objectives are
used frequently colour fading of the specimen occurs early, degrading the view
(contrast) of fluorescent images. So it is effective to use the shutter frequently to
avoid illuminating the specimen for a longer period than required.
11.1.6.2 Colour fading of the specimen can also be delayed using commercially
available colour fading preventing agent (DABCO, etc). The use of colour fading
preventing agent is recommended when you perform high-magnification
observation frequently.
★
Note that colour fading prevention agent cannot be used with certain specimens.
12. Switching on Electrical Source of the LED driven epi-florescence unit
•
Set the main switch of the power supply unit to “1” (ON). The LED diode will be at full
capacity immediately after ignition.
•
To avoid shortening the burner life, do not turn the burner off and on repeatedly
•
The LED Diode is at full temperature and efficiency after 30 seconds and the aluminium
holder can warm considerably after about 10 minutes, it is advisable to leave the unit off for
approximately 10 minutes before moving the unit to allow sufficient cooling to occur.
