InSitu Pro^™ Optical Heating and Cooling Stage is an experimental device that integrates microscopic observation with temperature control technology. It is widely used in materials science, physics, chemistry, biology, and other fields. By precisely controlling temperature while observing the microstructural changes of samples in real time, optical heating and cooling stages provide critical technical support for materials research and have enabled breakthrough progress in multiple disciplines.

Core Functions of Optical Heating and Cooling Stages

Precise Temperature Control

Supports a wide temperature range from low to high, with control accuracy up to ±0.1 °C.

Can simulate material performance under extreme conditions, such as phase transitions, thermal expansion, and thermal decomposition.

Microscopic Observation

Equipped with high-magnification microscopes (e.g., optical, confocal, or infrared microscopes) to observe microstructural evolution during heating and cooling.

Supports multiple observation modes including transmission, reflection, and fluorescence, adaptable to various material types.

Dynamic Analysis

Integrates cameras and image processing software to record morphology changes at different temperatures, generating dynamic videos or time-series images.

Can be combined with other analytical techniques for multi-scale characterization.
