Filters

It is possible to insert up to two filters in the filter holder located under the lamphouse. The following
filters are available for use as required by the application.
ND2 filter:
ND8 filter:
NCB11 filter:
GIF:
Heat insulation filter:
Diffuser: For TS100LED MV/TS100LED-F MV, as a diffuser is inserted in the filter holder as standard,
only one more filter can be inserted.

Objectives

1
Ph codes
A Ph code (PhL, Ph1 or Ph2) is printed on each of the objectives for phase contrast microscopy.
Regardless of the magnification of the objective, be sure to insert the annular diaphragm having
the same Ph code as the objective in the optical path when performing phase contrast
microscopy. (The annular diaphragm must also be centered when using a centerable phase slider
before making observations.)
Although Nikon also offers an objective for phase contrast microscopy with a Ph code of Ph3, this
objective is for high-magnification applications and cannot be used for phase contrast
observation with this microscope.
2
NAMC codes
An NAMC code (NAMC1, NAMC2 or NAMC3) is printed on each of the objectives for NAMC
microscopy. Regardless of the magnification of the objective, be sure to insert the slit diaphragm
having the same NAMC code as the objective in the optical path when performing NAMC
microscopy. (The slit diaphragm position must also be aligned with the NAMC objective
modulator before making observations.)
4 Operation of Each Part
4 Filters
For brightness adjustment on normal microscopy and photomicrography.
Reduces light quantity to 1/2. (Approx. 50% transmissivity)
For brightness adjustment on normal microscopy and photomicrography.
Reduces light quantity to 1/8. (Approx. 12.5% transmissivity)
For correcting the color temperature on normal microscopy and on color
photomicrography (day light type).
Remove this filter from the optical path when making photomicrography
with tungsten type color film or monochrome film.
Green interference filter.
For improving the contrast in microscopy with monochromatic light and in
monochrome photomicrography.
For reducing the influences of heat rays in the illumination light on the
sample.
Use the heat insulation filter for a sample quite sensitive to heat, though
the microscope has a built-in heat insulation filter.
