The equipment enables multi-field coupling tests in optics, electricity, and high/low-temperature control. It is equipped with a custom adapter plate for stable connection to on-site optical systems, effectively suppressing interference from vacuum vibrations on micro-area observation. Additionally, the 9 mm objective lens working distance supports optical observation at 50× magnification.
To expand the equipment's applications, electrical testing can be performed in two scenarios:
(1) Samples integrated with micro-electrodes on a PCB board can be directly connected for testing.
(2) After removing the PCB board, the equipment can function as a standard optical Heating/Cooling stage.
The device comes with electrical interfaces, allowing it to be connected to semiconductor parameter analyzers for leakage current testing as low as fA level. To meet the demands of high-magnification objective observation, the equipment also integrates an independent gas path system. It supports vacuum testing and can be filled with inert gas after pre-vacuum for temperature-controlled experiments, further reducing vibration impact on high-resolution observation.
