Installation example (Camcorde)
1. Attach one camera stand to the bottom of the Light Box and attach the other one to tripod mount at the bottom of the cam-
corder. Next, adijust the height of each camera stand(using coares control) so that the central point of the emission face of the
Light Box aligns with the central point of the camcoder's lens.
2. Detach the end of the collimator (Infinity Adjustment Lens). Be sure to loosen the Light Box's clipping knob before attaching
the collimator to the Light Box. Screw the end of collomator into the rotary ring one the front of the Light Box to attach.
3. Attach the other end (lens side) of the collimator to the filter mounting screw of the camcorder's Lens. If it dose not fit, use the
step-UP ring provided with the collimator.
4. Load the compact transmission chart (gray-scale/color chart) in the chart holder and insert the chart holder into the chart slot.
5. Connect the DC regulated power supply (DC 12V ±0.2V, Aapprox. 2.0A) to the Light Box using the provided DC cord (red (+),
black (-)) and turn on the power switch at the rear of the Light Box.
6. While shooting the chart with the camcorder, adjust (using fine control) the chart holder posiyion as well as the height of the
Light Box an camcorder until the desired angle of view is achieved.
* Hint:
Tightening the clipping knob fixes the rotary ring firmly.
When it is completely tightened, the collimator attached to the rotar
ring is at right angles to the emission face of the Light Box or chart.
If the collimator cannot be attachedto the camcorder, try tightening
the clipping knob to compensatefor shearing of the optical axis in
the collimator.
On the other hand, if the collimator can be attached to the cam-
corder, try loosening the clipping knob slightly to make a little room
around the clipping knob.
Optical Filter (Made by Triacety cellulose)
Camcorder adjustment requires a commercially-available a color temperature conversion filter. For all kinds of thin film filters,
use the provided filter mount. To make a slip-in filter with the desired optical characteristics, follow the procedures below.
To use a slip-in filter, insert i into the Light Box filter slot. It is possible to insert 7 slip-in filters at a time into the filter slot.
<How to Make a Slip-in Filter>
1. Cut the desired optical filter to 45mm~45mm.
2. Remove the seal at the rear of the filter
mount,stick the optical filter in the filter mount
(over the hole), then fold the filter mount in half.
