On-Site Testing of Ultra-High-Temperature Heating Stage Integrated with Timegate Time-Gated Raman Spectrometer
GoGo Instruments' newly launched Ultra-High-Temperature Heating Stage H1500T is designed for studying the optical properties of samples under variable temperatures, characterizing how optical performance evolves with temperature. Utilizing resistive heating, it achieves precise control from room temperature (RT) to 1500°C. When integrated with optical equipment (e.g., microscopes, Raman spectrometers), it enables in situ variable-temperature testing. The stage features an adjustable design for optimized sample observation, making it ideal for high-temperature Raman applications.

The Timegate Time-Gated Raman Spectrometer combines picosecond pulsed lasers, time-gating technology, and SPAD array detectors. By precisely controlling laser pulse emission and detection windows, it effectively suppresses fluorescence interference, successfully separating fluorescence signals from Raman signals. This technology allows stable operation even under visible light or intense high-temperature thermal radiation, providing researchers and industries with a powerful analytical tool.

In scientific testing, the combined application of the ultra-high-temperature heating stage and time-gated Raman spectrometer facilitates performance testing and analysis of materials under extreme temperatures.
At the Institute of Physics, Chinese Academy of Sciences, GoGo Instruments’ H1500T stage integrated with the Timegate Raman spectrometer was used to test manganese dioxide (MnO₂) and yttrium vanadate (YVO₄) crystals. Raman spectra were collected across temperatures from RT to 1500°C. As the stage temperature increased, the time-gated Raman spectrometer demonstrated its unique advantages: effectively eliminating interference from fluorescence and high-temperature blackbody radiation while accurately capturing Raman spectra under extreme conditions.
