Title:
THERMAL INSULATION DEVICE FOR MICROSCOPE
Document Type and Number:
WIPO Patent Application WO/2024/047889
Kind Code:
A1
Abstract:
[Problem] The stage of a microscope has an opening portion through which the bottom portion of a culture vessel containing a specimen is exposed toward the underside of the stage. Therefore, the specimen is easily affected by room temperature. In particular, in an inverted microscope, heat is more easily absorbed by an objective lens which has been cooled at room temperature. [Solution] A cover 9 surrounds an opening portion b1 of a stage B and objective lenses C along with a revolver D located at the root thereof and the opening portion b1 of the stage B is closed by a bottom portion e1 of a culture vessel E such as a well plate placed on the stage B. The cover 9 thereby forms a closed space 51 together with the bottom portion e1. The closed space 51 is entirely heated by warm air blown from a warm air blowing mechanism 19 and the warm air is blown out from a lateral direction toward the periphery of the revolver D below the objective lenses C and the opening portion b1. Thus, the lower-side space of the opening portion b1 is intensively heated so that the revolver D and the objective lenses C mounted thereto are surrounded by warm gas. Accordingly, not only the bottom portion e1 of the culture vessel E but also optical components are heated gradually and evenly.
