Attachment of Collimator
(Collimator: Infinity Adjustment Lens)

It is possible to screw up a collimator to the Light Box.
And it is very easy to compensate for the slant (shear of
the optical axis) caused by the weight of the collimator
itself.

For easy and quick replacement of the charts, the light box
is equipped with the slot and the chart holder.
Also, it is equipped with the slots for optical filters, one for
color temperature conversion filters, and one for color
compensation filters.
It is very convenient to set up for a color condition
according to adjustment procedure.

To prevent the temperature from rising inside the Light Box
and to extend the life of the lamp, it is equipped.

1. Attach one camera stand to the bottom of the Light Box

and attach the other one to the tripod mount at the bottom
of the camcorder. Next, adjust the height of each camera
stand (using coarse control) so that the central point of the
emission face of the Light Box aligns with the central point
of the camcorder 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
collimator into the rotary ring on 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 does 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 12 V ± 0.2 V,

approx. 1.7 A) 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 position as well as the height
of the Light Box and camcorder until the desired angle of
view is achieved.

Tightening the clipping knob fixes the rotary ring firmly.
When it is completely tightened, the collimator attached to
the rotary ring is at right angles to the emission face of the
Light Box or chart.    If the collimator cannot be attached to
the camcorder, try tightening the clipping knob to
compensate for shearing of the optical axis in the collimator.
On the other hand, if the collimator can be attached to the
camcorder, try loosening the clipping knob slightly to make a
little room around the clipping knob.

(Made by Triacetyl cellulose)

Camcorder adjustment requires a commercially-available a
color temperature conversion filter and a color compensation
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 it into the Light Box filter slot. It is
possible to insert 7 slip-in filters at a time into the filter slot.

1. Cut the desired optical filter to 50 mm x 50 mm.
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.

3. It is recommended that you write the filter factor on the

filter mount.
