    Applications of Filters

(Fig. 23)

As necessary up to two filters may be individually inserted into the filter
insertion positions @ and ². Insert each filter with the marked side facing
toward the observer.
As you insert the filter, you will hear two clicks. At the first, the filter is in the
empty position, and at the second the filter is engaged in the light path.

Usable Filters

Mirror Unit

Field Iris

Aperture Iris

Reflected light brightfield

BF

U-MBF3

Adjust as required.

Reflected light darkfield

DF

U-MDF3

Must be open.

Applications

U-25FR (Frost filter)

To eliminate uneven illumination.

U-25LBD
(Color temperature conversion
filter)

To convert the color temperature of
the source to the color temperature
of daylight. Used for comfortable
observation and when taking color
photographs.

U-25IF550 (Green filter)

To increase contrast during mono-
chrome observation. Used when tak-
ing monochrome photographs.

U-25ND25-2
(Neutral Density filter)

To adjust illumination brightness.
 (Transmittance 25%)

U-25ND6-2
(Neutral Density filter)

To adjust illumination brightness
 (Transmittance 6%)

@

@

U-25L42

To prevent the polarizer burning
when a light source with high in-
tensity is used.

U-25Y48 (Yellow filter)

To achieve good contrast for semi-
conductor wafers.

U-25ND50-2
(Neutral Density filter)

To adjust illumination brightness.
 (Transmittance 50%)
