on microscope components
2.5.1
Binocular photo tube 30°/23
(100:0/0:100)
The photo port (
2
) of the binocular tube
can be used to mount a reflex camera, a
microscope camera or a video camera with the aid
of appropriate adapters.
Using the shift knob (or the push-pull rod on other
photo tubes), the light can be directed to the
eyepieces or to the mounted camera.
−
Shift knob (
3
) in forward position
(eye symbol):
100% light to the eyepieces
−
Shift knob (
3
) in back position
(camera symbol):
100% light to the camera
−
Push-pull rod (
1
) pushed in:
Eyepiece shutter is closed.
−
Push-pull rod (
1
) pulled out:
Eyepiece shutter is open.
−
Whenever you want to take photos with a long exposure time, we recommend that you block any
ambient light from entering the eyepieces by using the tube shutter or the eyepiece cover (included
in the dust protection kit). If neither is available, remove the eyepiece and place the included dust
protection caps over the eyepiece barrels.
−
Vary eyepiece distance by moving the eyepiece barrels apart or together.
NOTE
For polarization microscopy, we recommend using the Pol photo tube with upright image and
one eyepiece reticle (graticule).
