The Cryogenic Probe Station is a state-of-the-art 0-67GHz microwave-compatible 4K cryogenic probe station designed to meet the demanding requirements of advanced research and development in low-temperature physics, semiconductor testing, and microwave device characterization. This one-click controlled integrated cryogenic probe station offers exceptional precision and versatility, making it an indispensable tool for scientists and engineers working with ultra-low temperature environments ranging from 4 K to 420 K.

One of the standout features of this cryogenic probe station is its remarkable temperature stability, maintaining a precise ±1.20 mK fluctuation across the entire operating temperature range of 4 K to 420 K. Such stability is critical for experiments requiring highly controlled thermal conditions, ensuring that measurements remain consistent and reliable even during extended testing periods.

Equipped with a high-performance microwave probe capability, the station supports frequencies from 0 to 40 GHz with a K-type connector, and extends up to an impressive 0 to 67 GHz when using the 1.85 mm connector. This wide frequency range accommodates a broad spectrum of microwave applications, enabling detailed analysis of high-frequency devices and components with minimal signal loss and superior measurement accuracy.

Electrical integrity is another key attribute of this cryogenic probe station. It boasts an ultra-low electrical leakage current of less than 100 fA at 1 V, which significantly reduces noise and interference during sensitive electrical measurements. This feature is particularly important for researchers working with low-current devices or those requiring high precision in their electrical characterization.

The integrated optical microscope complements the probe station’s capabilities by providing continuous zoom functionality ranging from 0.75* to 3.75* magnification. This allows users to visually inspect sample surfaces and probe contacts with ease and precision, facilitating accurate positioning and alignment of probes on samples as small as 2 inches in diameter. The sample holder itself is designed to accommodate samples with diameters up to 51 mm, offering flexibility for a variety of experimental setups and sample sizes.

Designed for efficiency and ease of use, this 2-inch sample 4K-420K cryogenic probe station features a streamlined, one-click control interface that integrates all cryogenic and probing operations into a single, user-friendly platform. This integration reduces setup time and minimizes the risk of user error, allowing researchers to focus on data acquisition and analysis rather than complex equipment management.

In summary, the Cryogenic Probe Station represents a cutting-edge solution for anyone requiring precise temperature control, high-frequency microwave probing, and ultra-sensitive electrical measurements at cryogenic temperatures. Its combination of exceptional temperature stability, broad microwave frequency compatibility up to 67 GHz, ultra-low leakage current, advanced optical inspection capabilities, and flexible sample accommodation makes it ideal for a wide range of scientific and industrial applications.
