The in-situ microscopic electrochemical Raman spectrometer mainly consists of a Raman spectrometer, a potentiostat, a microscopic system, and a laptop. This product integrates the potentiostat with the Raman spectrometer, combining the power button and power supply, and packages the Raman spectrometer, potentiostat, and microscopic system together. All cables, optical fibers, and power lines are cleverly hidden inside the device or routed along carefully designed paths. This integrated design significantly enhances experimental efficiency by ensuring stable signal transmission while avoiding the clutter and complexity of external wiring, which could otherwise lead to errors.
The microscope module's stage is designed as a U-shaped movable platform with a wiring switch, optimizing the loading process of the Raman electrochemical cell and reducing the cumbersome task of wire clamping.
The in-situ microscopic electrochemical Raman spectrometer combines the advantages of electrochemical testing and Raman spectroscopy analysis. It enables real-time, in-situ monitoring of structural and property changes in materials during electrochemical processes without damaging the sample. This technology not only improves experimental accuracy and sensitivity but also broadens the scope of research, providing strong support for scientific research and technical applications across multiple fields.
Oceanhood’s self-developed Raman three-channel module supports Raman spectroscopy measurements at any three different excitation wavelengths, such as 532 nm, 633 nm, 785 nm, 830 nm, and 1064 nm. The module is equipped with an optical path switching system, allowing rapid switching between different wavelengths via software. It also supports overlay and comparative analysis of the collected Raman spectra. The probe on the module is plug-and-play, making it convenient for testing samples in unconventional forms.
◆ Flexible and portable: Equipped with 3 external interfaces for Raman modules, it supports the connection of a 785 nm Raman probe, which can be plugged and unplugged freely. It can be expanded to connect 532 nm and 1064 nm Raman spectrometers.
◆ The Raman probe adopts a tail fiber structure with a fiber length of 1.5 m. It uses an 8.5 mm stainless steel dual-lock corrugated tube with plastic coating, capable of withstanding a tensile force of 5 kg.m. The front-end detachable focusing lens has
