Reflection Mirror CH20-MM
}The reflection mirror is designed to be used in microscopic observation in a location where power supply is not available.
It makes it possible to use the natural light in place of the lamp bulb.

This accessory accommodates a filter with a diameter of 32.5 mm or the
CH2-DS darkfield ring.
1. Remove the daylight filter if it has been attached.
2. Push the filter holder 2 containing the desired filter 1 into the bottom of
@
the condenser until it clicks into place.

For other filters, contact Olympus.
Filters similar to the above having a diameter of 45 mm are also available
for insertion in the window lens.
1. Insert the darkfield ring in the CH2-FH filter holder in the same way as
inserting a filter.
2. The darkfield ring enables darkfield observation using an objective from
4X to 40X.
# The microscope should be installed near a window, in a place that
is not exposed to direct sunlight.
The eyepieces should be oriented toward the rear so that the reflec-
tion mirror receives the bright light. Loosen the observation tube
clamping knob and rotate the tube by 180°.
1. Fit the reflection mirror in the window lens of the microscope frame by
aligning the mounting tab.
2. Remove the daylight filter because it renders the image bluish under
@
natural light.
3. The reflection mirror 1 should be pointed toward the bright area. While
observing the image through eyepieces, adjust the orientation of the
reflection mirror.
}A planar reflection mirror is used normally. However, if the image bright-
ness is uneven or the outside view is visible in the image, use a concave
reflection mirror.
Application
Changes the light of the built-in lamp bulb (which is yellow-
ish) to natural light.
Reduces fatigue or provides specimen with contrast.
Converts the color of light for color photography (with a day-
light film).
