Title
(EN) TEMPERATURE CONTROL FOR MICROSCOPY
(FR) REGULATION DE TEMPERATURE POUR METHODE D'OBSERVATION AU MICROSCOPE
Abstract
(EN) A temperature control unit provides means for observing samples under microscopy at greatly elevated and greatly reduced temperatures. The temperature control unit is constructed to insulate a sample from ambient temperatures while providing a highly heat conductive substrate for the sample that provides for rapid heat transfer to/from the sample. A dry gas provides a positive pressure around the sample, as compared to atmospheric pressure to help prevent atmospheric contract with the sample.
(FR) L'invention se rapporte à une unité de régulation de la température qui permet une observation microscopique d'échantillons à des températures considérablement élevées ou considérablement basses. Ladite unité de régulation de la température est conçue pour isoler un échantillon de la température ambiante tout en fournissant à l'échantillon un support fortement conducteur de la chaleur qui assure un échange thermique rapide avec l'échantillon. Un gaz sec génère autour de l'échantillon une pression positive, comparée à la pression atmosphérique, qui permet d'empêcher le contact de l'échantillon avec l'environnement atmosphérique.
