This photochemical reaction DSC system enables the acquisition of the high sensitive and low noise sample data even the thin film and the minute sample by High Sensitivity Differential Scanning Calorimeter. Extremely high irradiation intensity is achieved by the irradiating the ultraviolet or visible light the sample and the reference right above. Irradiation intensity can be variable by light intensity at the source and continuous variable ND filter. Wavelength selection can be done easily by interference filter change. Irradiation time can be set by 0.1 sec by the versatile shutter controller. Shutter open / close can be done automatically and manually by PC.
