Motorized, 8-position FL excitation filter wheel
−
Coded and motorized filter wheel with 8 positions for dia. 25 mm filters especially for applications in
epi-fluorescence.
The filters can also easily be exchanged by the user:
•
Loosen both knurled screws at the bottom side of the filter housing and fold up the side.
•
Insert or replace filter and secure using the clamping ring.
•
Close the filter housing and tighten the knurled screw.
LED lamp voltage array
−
Indicates the present operating voltage of the halogen illuminator in 10 steps (3 ... 12 V).
−
In the programming mode, it indicates the speed of the stage movement in 10 steps.
Pilot lamp
−
The LED pilot lamp for the line voltage lights up when the instrument is switched on.
−
During initialization of the instrument after switch-on, the pilot lamp lights up in orange.
−
In the programming mode (see page 3-21), the pilot lamp lights up in green-orange.
Control for light intensity
−
Controls the DC voltage supply of the halogen illuminator in the range between 3 and 12 V.
−
Important note: When connected to the light manager, the control might be in one of the two stop
positions, although the light intensity on the instrument differs from the relevant values. To change
the light intensity, the control must be moved out of its stop position. Setting can then be performed
as usual.
Motorized focusing drive coarse / fine adjustment
−
Focusing knob for coarse or fine adjustment on both sides of the instrument
−
Average increments: 80 nm, reproducibility in the focusing range: 0.15 µm.
−
Overall lift: max. 25 mm.
