なければならず、余分な手間がかがる欠点があった。Furthermore, especially when circular crystal pieces 10.11.12 are cut out and used, it is difficult to distinguish the optical axis 3 of each crystal piece 10.11.12. The notches 10a, 11a, and 12a had to be formed in accordance with the above, which had the drawback of requiring extra effort.
また、矩形の水晶片４．５．６を形成する場合には、各
水晶片４．５．６を１枚ごとに別の型で作らなければな
