How to create Setting board of "Lens alignment chart" and "Viewer"
1. Summary
1-1: In order to get necessary data for lens alignment, this board is created to use for setting a special chart and light
viewers (for chart illumination), while taking pictures of the special chart with a digital camera.
2. Preparation
2-1:Prepare a board (760 × 880 × 20 mm) or 2 package cardboard boxes (size 2.33).
(Note) Because you have to cut out the shape to embed light viewers, choose package cardboard boxes (size 2.33) or
material which can be easily cut. － ref. Fig. 1 on next page
3. Procedure （In this document, 2 package cardboards are used）
3-1: As for the 1st flattened cardboard box (size 2.33), check the positions for embedding the light viewers, and cut out
the shape at 5 locations (shaded parts/size 154 × 245 mm) as shown below. － ref. Fig. 2 on next page
(Note) Cutting the shape slightly smaller than the actual size of viewers makes it easier to fit the positions of viewers
tightly.
3-2:Put the 2nd flattened cardboard box (size 2.33) and the above cut-out 1st cardboard together as one, and fix them by
taping at 4 sides. － ref. Fig. 3 on next page
3-3:Then as for the 2nd flattened cardboard box, cut out the shape again by matching the cut-out size of 3-1 for each
viewer. － ref. Fig. 4 on next page
3-4:Reinforce the edges of cut-out parts with tape.
(Note) To prevent viewers falling off, secure them with tape around the edges. － ref. Fig. 5 on next page
3-5: On the board surface that was created in "3-4", apply the matte-black paint or put a less-reflective cover.
3-6: Attach the lens alignment chart (J19128) on the setting board with the surface of tool-number seal being on the back
side, or attach it by removing the tool-number seal. There is no difference in front-back both sides of the chart.

4. Prevent Viewers from falling off (In this document, 2-mm width Velcro tape is used.)
4-1: As shown above, when viewers are embedded, secure them with square pieces of Velcro tape (hook and loop
fastener) on the back of the cardboard to prevent viewers falling off.
