多数の非結像集光作用のあるフレネルレンズもしくは反射鏡と放射流束センサーを組み合わせたものを全球方向に配置し、カバー材料に測定対象とする放射の波長領域での透過率が高いという選択透過性を持った光学フィルタを用いた構造の放射流束計を提案する。例文帳に追加

This radiation flux meter has a structure, wherein many combinations of a Fresnel lens or a reflecting mirror having an image non-forming condensing function and a radiation flux sensor are arranged in the spherical directions and an optical filter, having selective transparency with high transmittance in a wavelength region of a radiation, an object of measurement, is used for a cover material. - 特許庁

波長の異なる複数の光源からの光束を、波長選択性を有する光学部品で分離、合成して複数の対物レンズに導く光ピックアップにおいて、対物レンズに設計波長以外の光が漏れ込んで対物レンズに黒点等を発生させ、収差、透過率を悪化させることを防止する。例文帳に追加

To provide an optical pickup separating/synthesizing luminous fluxes from a plurality of light sources having different wavelengths by an optical component having wavelength selectivity, to guide them to a plurality of objective lenses, which prevents deterioration in aberration or transmittance due to black points generated in an objective lens when light of a wavelength other than a design wavelength enters the objective lens. - 特許庁
