Description
さらに好ましくは、
０．２＜Ｄｙ４Ｍ＜０．４（１／ｍｍ） ・・・（４−４）
なる条件式を満足することがより重要であり、観察画角が４０°を越える場合により良好な像を得るうえで重要となってくる。
More preferably,
0.2<Dy4M<0.4 (1/mm) (4-4)
It is more important to satisfy the following condition, which becomes important in order to obtain a better image when the observation angle of view exceeds 40° .
この時、接眼光学系の、焦点距離Ｆｘ６Ａと焦点距離Ｆｙ６Ａが次に述べる条件式を満足することが重要になる。
１０＜Ｆｘ６Ａ＜５０（ｍｍ） ・・・（６−１）
１０＜Ｆｙ６Ａ＜５０（ｍｍ） ・・・（６−１" ）
Ｆｘ６Ａ、Ｆｙ６Ａに、上記条件式の上限の５０を越えてしまうと、観察画角が小さくなるとともに光学系全体が大きくなりすぎてしまう。下限の１０を越えると、観察者眼球や観察者顔面と、接眼光学系との干渉が生じてしまい、補正しきれない量の収差も発生してしまう。これら条件は、画像表示素子の大きさによって、最も良い値が異なるので、画像表示素子の大きさにより、それぞれベストの値をとることが重要である。
In this case, it is important that the focal lengths Fx6A and Fy6A of the eyepiece optical system satisfy the following conditional expressions.
10<Fx6A<50(mm)...(6-1)
10<Fy6A<50 (mm) ... (6-1")
If Fx6A and Fy6A exceed the upper limit of 50 of the above condition, the observation angle of view will become small and the entire optical system will become too large. If the lower limit of 10 is not reached, interference will occur between the observer's eyeball or face and the eyepiece optical system, resulting in the generation of aberrations that cannot be fully corrected. The optimal values for these conditions will vary depending on the size of the image display element, so it is important to obtain the best values for each depending on the size of the image display element.
