laser diffraction analysisとは 意味・読み方・使い方

The method for inspection includes a step of irradiating an observation object of a rear surface of a sample 7 with an infrared laser beam 12 emitted from a laser beam source 1 and incident upon a diffraction lens 4 as a Bessel beam 13, detecting its reflected light 14 by a photodetector 11, and performing analysis.例文帳に追加

レーザ光源１から発せられた赤外レーザ光１２は、回折レンズ４に入射してベッセルビーム１３となり試料７の裏面の観察対象に照射され、その反射光１４は光検出器１１により検出されて、解析が行われる。 - 特許庁

The composite particle is composed of smaller particles and larger particles, wherein the smaller particles are supported on the larger particles, and the smaller particles are titanium oxide-silica composite fine particles having 0.02-0.5 μm of average particle size calculated from the BET specific surface area, and the larger particles have 2-200 μm of average particle size measured by laser diffraction/scattering type particle size analysis.例文帳に追加

小粒子がＢＥＴ比表面積換算粒径で０．０２μｍ〜０．５μｍの平均粒径を持つ酸化チタン−シリカ複合微粒子であり、この小粒子がレーザー回折／散乱式粒度分析法によって測定される平均粒径２〜２００μｍの大粒子に担持されていることを特徴とする複合粒子。 - 特許庁
