Operation for the Illumination

To select the episcopic illumination or the diascopic illumination
When the epi illuminator and the episcopic illumination
lamp house are attached, the epi/dia selector switch on
the left side of the microscope can be used to select
either the episcopic illumination or the diascopic
illumination. Each time the switch is pressed, the
illumination toggles and the indicator for the selected
illumination lights.
* When the epi illuminator is not attached, the switch
can be used to turn on/off the diascopic illumination
lamp.
Brightness control and lamp power supply
When the brightness control knob is turned, the
brightness of the illumination selected by the epi/dia
selector switch is changed.
* To use an external light source, adjust the brightness
at the light source side or use the ND filters on the
microscope or the epi illuminator to adjust the
brightness.
A switch is included in the brightness control knob to
turn on/off the lamp. Turn the brightness control knob to
the far side (counter clockwise) and position to the OFF
to turn off the illumination selected by the epi/dia
selector switch.
* When an external light source is used, the
illumination is turned on/off at the light source side.
Color temperature shift affected by the brightness control
Adjusting brightness with the brightness control knob will affect the lamp color temperature
and alter the color balance of the image. If accurate color reproduction is critical, adjust the
brightness control knob to the "three o'clock" position. In other words, turn the index mark
to the horizontal position. (See the figure above.) In this adjustment, the lamp voltage
becomes about 9 V. And you can get the best color reproduction with NCB11 filter. When
adjusting the brightness, use ND filters.
Power indicator
The color of the power indicator changes in accordance with the halogen lamp condition. When the
halogen lamp is lit, the indicator is green. When the brightness control knob is set to the OFF
position, the indicator is orange.
