Adjusting the Brightness of a Diascopic Image
The brightness of a diascopic image can be adjusted by changing the voltage of the lamp with the dia-illumination
brightness control knob or by removing/inserting ND filters from or into the optical path.
1.1
Adjustment with the Dia-illumination Brightness Control Knob
Turning the dia-illumination brightness control knob changes the

Adjusting the dia-illumination lamp
When using Ci-S (to retain the color balance of the image)
Adjusting brightness with the brightness control knob will affect the lamp color temperature and alter the color balance
of the image. If accurate color reproduction is critical, set the brightness control knob to the
position and use the
ND filters for brightness adjustments.
1.2
Adjustment with the ND Filter (for Ci-S)
ND filters are used to adjust light intensity. Higher filter numbers
correspond to lower transmittance (i.e., darker images). The colo
r
balance of the image will not change.
Ci-S has built-in ND filters (ND4 and ND8).
Pushing the each filter IN/OUT switch inserts the corresponding
ND filter into the optical path.
ND4: Reduces light intensity to 1/4.
ND8: Reduces light intensity to 1/8.
ND4+ND8: Reduces light intensity to 1/32.

Adjusting the brightness with ND filters
Placing the ND filers over the field lens
You can add an ND filter by placing the ND filters over the field lens or mounting the filter cassette holder onto the field
lens part.
The filter cassette holder can house up to three φ45 mm filters with a thickness of up to 3 mm. Pushing in the filter
IN/OUT lever inserts the ND filters into the optical path. In addition, one filter can be placed on the filter cassette holder.
The filter cassette holder cannot be used with a simple polarizer, polarizer unit for first-order red compensation, or the
spacer for the nosepiece.
