Color temperature of illuminator
Adjusting brightness with the brightness control dial will affect the lamp color temperature and alter the color
balance of the image.
When accurate color reproduction is critical to observe the color balance of the sample or to shoot/record its
image, set the brightness control dial to the index as shown (at the 3 O’clock position of the dial in the Figure
3.2-1) and place the NCB11 filter into the optical path. In this condition, the voltage applied to the lamp is
approximately 9 V and the color reproduction is improved maximally. To adjust the brightness of the
illumination, use ND filters. (See 3.10.)
