Transmitted Light Hot Stage Microscopy in the Temperature Range -180°C to 600°C
A hot stage (Model TLHS) is described which allows direct observation of a sample by transmitted light, as it is heated or cooled at a controlled rate over the range from -180°C to 600°C. The sample can be viewed in normal or polarised light and the intensity of the transmitted light measured using a photocell and displayed on a recorder together with the linearised sample temperature. The performance of the unit is illustrated by reference to ICTA-NBS Temperature Standards.
