(2) (where Ns is the refractive index of the substrate; Nh is the refractive index of the thick film; Nf is the refractive index of the middle layer; and Df is the thickness of the middle layer) between the substrate and the thick film.例文帳に追加

Ｎｓ＜Ｎｆ＜Ｎｈ 又は Ｎｓ＞Ｎｆ＞Ｎｈ （１） Ｎｆ・Ｄｆ＝０．２５λ （２） （Ｎｓ：基材の屈折率、Ｎｈ：厚膜の屈折率、Ｎｆ：中間膜の屈折率、Ｄｆ：中間膜の膜厚） - 特許庁

A refractive index distribution of the thermal lens 12 is approximated by a Gauss distribution, and the chromatic aberration df and the aperture number NA of the rod lens 10, a depth (thickness) t and a refractive index difference dn of the thermal lens, and the aperture radius rad and the PD distance L of the PD 11 are determined to make maximum a TML output calculated by an actual beam tracking.例文帳に追加

熱レンズ１２の屈折率分布をガウス分布で近似し、実光線追跡により算出されるＴＬＭ出力を最大とするロッドレンズ１０の色収差ｄｆ及び開口数ＮＡ、熱レンズ１２の深さｔ及び屈折率差ｄｎ、ＰＤ１１の開口半径ｒａｄ及びＰＤ距離Ｌを決定する。 - 特許庁
