Chapter 4 Setting Up the Microscope
4.2 Setup Procedure
2-31
2
Attach the dichroic mirrors (photo activation illuminator unit only).
It is necessary to attach a dichroic mirror (optical path switch mirror), which switches between laser light and
episcopic illumination, inside the photo activation illuminator unit. Since the attachment does not ship with a
mirror attached, you must attach one following the procedure below.
You can also change the light intensity ratio of laser light and episcopic illumination by switching the dichroic
mirror and operating the optical path switch lever.
Ordinarily, you should attach a total reflection mirror. When using a total reflection mirror, operating the
optical path switch switches between 100% laser light and 100% episcopic illumination.
WARNING
To prevent hazardous laser emission from the mirror replacement opening, turn off the laser
power before replacing mirrors.
