Purpose
Converts the illumination light of
the halogen bulb to the daylight
color.
Converts the illumination light of
LED to the illumination color of
the halogen bulb.
Increases the contrast of the
observed image.
Contrast filter for semiconductor
wafer observation
Adjusts the brightness of the light
source.
(Transmittance: 6%/25%/50%)
The light intensity decreases,
but the illumination without
unevenness can be obtained.
Cuts the ultraviolet ray to prevent
the tarnish on the polarizer caused
by the mercury lamp housing.
Used as a shutter to interrupt
the observation for a short time
when using mercury lamp
housing.
