Also known as an ultramicroscope. A microscope that uses a slit or condenser to illuminate particles from the side or diagonally downward, making them shine in a dark field due to the Tyndall effect. The resolution is less than 1/100 of that of a normal optical microscope, reaching a few μm. It is used to study the presence of colloidal particles, Brownian motion, the internal structure of cells, etc. Invented by Siedentop and Sigmondy in 1903. → Related topics Microscope | Condenser Source : Heibonsha Encyclopedia About MyPedia Information |
限外顕微鏡とも。スリットまたは集光器により側方または斜下方から微粒子を照らし,ティンダル現象により暗視野中に輝いて見えるようにした顕微鏡。分解能は普通の光学顕微鏡の1/100以下,数μm程度に達する。コロイド粒子の存在,ブラウン運動,細胞の内部構造などの研究に用いる。1903年ジーデントップとシグモンディが考案。 →関連項目顕微鏡|集光器 出典 株式会社平凡社百科事典マイペディアについて 情報 |
