INFO
Using reflected light on transparent samples may create reflections which lead
to inappropriate illumination of the sample.
3.6.2 Adjusting the Color of Reflected Illumination
Primotech microscopes come with the conversion filters to change the color
temperature or profile of the reflected illumination. Conversion filters can be used,
for example, to make the color profile of the LED light similar to that of a halogen
light.
Procedure
1
To use a conversion filter with reflected light, insert the filter slider into the
vertical slot on the intermediate tube.
2
To use a conversion filter with transmitted light, place the conversion filter disc
on the luminous field diaphragm.
3.6.3 Using Oblique Reflected Illumination
You can adjust the reflected illumination (if available) so that the light is projected
obliquely onto the sample. This enhances the appearance of height differences on
its surface.
Procedure
u
To change the direction of the oblique illumination, turn the wheel on the
intermediate tube.
The wheel has three settings:
– Illumination from the left
– Standard illumination / no oblique illumination
– Illumination from the right
