Using The Nd Filter - Konica Minolta CS-3000HDR Instruction Manual

Using the ND Filter

Use the ND filter in the optional accessories to measure high-luminance objects.
If the ND filter is attached, the measurement value must be compensated for the filter transmittance.
This compensation coefficient is attached to the ND filter. After setting up the instrument using the
CS-S30 software for spectroradiometers that comes standard with the instrument, an ND filter can be
selected as an accessory to obtain measurement values corrected by the correction coefficient. For
details on how to set up using the software, see the CS-S30 instruction manual.
Setting the wrong ND filter will lead to inaccurate measurement.
Moreover, do not use the ND filter with the closeup lens and illuminance adapter. as this will lead to
inaccurate measurement.
Note that an extra ND filter is built into this instrument. There are three setting options for use or non-
use of this built-in ND filter: [AUTO] for switching automatically depending on the luminance of the
object, [OFF] for constant non-use, and [ONE] / [TWO] for constant use (See p.28).
* EXT-ND : OFF, EXT-ND10 (1/10), EXT-ND100 (1/100)
* Factory default setting : EXT-ND: OFF, IN-ND: AUTO
