Adjustment With Nd Filters - Nikon Eclipse Ni-E Instruction Manual

Adjustment with ND Filters

3.2
There are two methods for adjusting the brightness with ND filters: bringing/removing the main body's internal ND filters
in/from the optical path, or operating the motorized ND filter wheel attached between the main body and dia-illumination.
Using ND filters in the main body
ND filters are used to adjust light intensity. Higher filter numbers
correspond to lower transmittance (i.e., darker images). The
color balance of the image will not change.
The Ni-E has a built-in filter cassette, with ND8, ND32, and
NCB11 filters attached. Pressing the IN/OUT switch for ND8 or
ND32 to the [IN] side will bring the corresponding ND filter into
the optical path.
ND8: Reduces light intensity to 1/8.
ND32: Reduces light intensity to 1/32.
ND8+ND32: Reduces light intensity to 1/256.
Adding or changing ND filters
The filter cassette has an empty filter slot which can be used for an additional ND filter. The filter already attached can
also be removed and replaced with another filter. (See Chapter 1 "3 Assembly Method - 19 Replace the ND filter" in the
"Assembly/Maintenance" instruction manual.)
Also, up to two φ45 mm filters can be placed on the field lens.
Motorized ND filter wheel
See the Ni-E (Focusing Stage System) instruction manual for details of the motorized ND filter.
