Using The Polarizer Turret; Switching The Optical Path Of The Tube - Nikon Eclipse Ni-E Instruction Manual

Using the Polarizer Turret

The polarizer turret is attached to the field lens and used for
differential interference contrast microscopy. The turret has four
holes with the FN-P polarizer for visible range (λ=430 nm to 770
nm) and the FN-IRP polarizer for infrared ray (λ=850 nm to 950
nm) attached. The remaining two holes are empty and φ33 filter
can be attached.
In the standard configuration, an NCB filter is attached.
See Chapter 1 "3 Assembly Method – 7 Attach the polarizer
turret" in the "Assembly/Maintenance" instruction manual for
details on how to attach the polarizer.
Turn the turret and bring the polarizer into the optical path for
differential interference contrast microscopy. Make sure the
turret is stopped at a click-stop position when switched.
To adjust the contrast, turn the knurled ring on the right of the
polarizer turret to change the direction of the polarizer.
Provided adjustment tool for the 1/4 lambda plate orientation is
used for orientation adjustment when the polarizer is attached.
(See Chapter 1 "3 Assembly Method – 7 Attach the polarizer
turret" in the "Assembly/Maintenance" instruction manual.)

Switching the Optical Path of the Tube

The motorized quadrocular tilting tube has three optical paths,
directed to the binocular, tube adapter, and rear port. Pressing
an optical path button directs 100% of the light to the
corresponding optical path. When a button is pressed, it will light
up to indicate the selected optical path. The B/F/R optical path
switch on the ergo controller can also be used to switch the
optical path. See the Ni-E (Focusing Stage System) instruction
manual for details of the ergo controller.
• BINO optical path button:
• FRONT optical path button: 100% to tube adapter
• REAR optical path button:
