4 Using the Filter Turret
(Fig. 5)
}Filters with a diameter of 32 mm can be inserted in positions 1 to 4.
1. Filter positions 1 2 are rotatable. When the 32PO or 32POIR polarizer is
placed in either position, the polarizer can be fixed by a push ring.
}When filter position 1 is engaged in the light path, the polarizer clamping
knob 5 comes at the front where the operation is easy.
2. Filter position 3 accepts any type of 32 mm filter.
# When using two filters together, the thickness of the lower filter should
be no more than 2 mm. Otherwise, the upper filter may drop during
rotation.
3. Filter position 4 accepts the 32BP775 or 32IR900 IR filter. As the filter
cannot be inserted unless the filter slider is removed, remove it by releasing
the insertion/removal stopper below the slider and loosening the slider
clamping screw using the provided Allen screwdriver.
4-2 Focusing Block
}The same effect as the focus adjustment knob on the microscope frame can also be obtained using the U-FH focus
adjustment knob unit. However, when the microscope is used stand-alone while the cable to the U-FH is connected, the
focus adjustment is available only from the focusing knob on the U-FH.
