principal angle of incidenceとは 意味・読み方・使い方

A maximum angle θ1 out of angles formed between respective principal rays going from a first imaging system toward a second imaging system and a normal of a reduction-side conjugate surface and an angular difference θ2 between an incidence angle and an exit angle in the second imaging system, of the ray emitted at this maximum angle are prescribed so as to be within prescribed ranges.例文帳に追加

また、第１結像系から第２結像系に向かう主光線の各々と縮小側の共役面の法線とのなす角度のうち最大角θ１、およびこの最大角で出射された光線の第２結像系における入射角と出射角の角度差θ２、が所定範囲となるように規定されている。 - 特許庁

PD, which denotes a distance measured along an optical axis AX between the entrance pupil and the first plane, TT, which denotes a distance measured along the optical axis between the first and the second plane, and R (rad), which denotes an angle of incidence of a principal ray incident on the first plane, meet a condition, -14.3<(PD/TT)/R<-8.3.例文帳に追加

入射瞳と第１面との間の光軸（ＡＸ）に沿った距離ＰＤ、第１面と第２面との間の光軸に沿った距離ＴＴ、および第１面に入射する主光線の入射角度Ｒ（rad）は、−１４．３＜（ＰＤ／ＴＴ）／Ｒ＜−８．３の条件を満足する。 - 特許庁

By setting a fixed condition as to the convergence distance of each converging point of the luminous flux cross section including principal ray in accordance with the passing position of the luminous flux passing through the 1st optical system (30), the skew incidence optical system having a half angle of ≥60° can be obtained with a comparatively simple constitution, irrespective of the kind of an optical element in use.例文帳に追加

第１光学系（３０）を通過する光束に関し，その通過位置に応じて，主光線を含む光束断面の各収束点の収束距離に一定の条件を課すことで，使用する光学素子の種類に関わらず，半角６０°以上の斜入射光学系を比較的簡単な構成で実現することが可能となる。 - 特許庁
