摘要： The apparatus is attached to a thermal analyzer including a pair of sample containers and a heating furnace having a window or an opening through which at least the measurement sample can be observed, and includes an attachment unit, a light source, a polarizer constituting a polarizing filter that polarizes irradiation light emitted from the light source, a camera, a half mirror, a rotation mechanism and an analyzer constituting a polarizing filter configured to polarize reflected light through the half mirror and to introduce the resulting polarized light of the reflected light into the camera, in which the polarized light irradiates the sample after passing through the window or opening and then reflects from the sample wherein the analyzer, the half mirror, and the light source are fixed to a fixing member and the rotation mechanism rotates the fixing member in a polarization direction of the analyzer.

摘要： Disclosed is an apparatus for acquiring polarized images attached to a thermal analysis apparatus including a pair of sample containers housing a measurement sample and a reference sample, respectively, and a heating furnace, configured to observe at least the measurement sample through a window or an opening of the heating furnace, and including an attachment section attached to the thermal analysis apparatus, a light source, a polarizer configured to polarize light emitted from the light source, a camera and an analyzer polarize light reflected from the measurement sample or the reference sample to enter the camera after the measurement sample or the reference sample is irradiated via the window or the opening with polarized light transmitted through the polarizer. A first optical path of the polarizer and a second optical path of the analyzer are not parallel, and both the polarizer and the analyzer are rotatable.
