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), when taking pictures of the special chart with a digital camera. 2. Preparation 2-1:Prepare a board (760 x 880 x 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 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 x 245 mm) as shown below. � ref. Fig. 2 (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 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 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 � 3.5: Blacken around the setting board (with black spray, etc).
