At the heart of all PanScan systems is the remarkably robust PanScan scan head. While designed and optimized for Low Temperature and Magnet fields, it is extremely versatile in numerous demanding settings. Compact, rugged, capable of atomic resolution in or out of high-Tesla environments or temperatures from mK to 400 K. Operates from ambient to UHV. PanScan scanners use industry-standard flag-style sample plates. PanScan offers a wide variety of important practical features, such as 4 electrical contacts on the sample stage (standard); internal temperature sensor; internal sample heater for small localized temperature tweaks; large rear opening in the body to view tip/sample approach; and 4 symmetrical openings around the body for in-situ sample deposition or optical access to the tip/sample junction. Compact and so adaptable – the perfect fit for the Freedom closed cycle cryostats and Freedom Tesla magnet bores or integrated into 3rd party bath cryostats, or dropped in or bolted-on as a multi-functional SPM for homebuilt systems.

Introducing the PanScan Freedom II New Frontiers in Performance and Flexibility Building on the success of the original PanScan Freedom, RHK Technology's latest PanScan Freedom II (PSF II) redefines cryogen-free performance, combining advanced thermal, magnetic, and optical capabilities to a new level in a versatile, compact platform. The original PanScan Freedom was the industry's first cryogen-free SPM and set a standard for mechanical stability and noise resistance. Cutting edge performance was repeatedly achieved in upper floors of buildings and other sub-optimal laboratory environments. The PanScan Freedom II advances this legacy. It delivers 5 K base temperature operation, providing liquid-helium performance with none of the complexity or costs. An integrated 7 T magnet and single cryogen-free cryocooler provides the capabilities of a wet system without the cost or complexity. Unobstructed optical access supports direct light injection/collection and precise probe visualization. An optional sample scanning module allows dual scanning modes—probe-scanning (up to 1.5 μm) and sample-scanning (up to 15 μm x 15 μm)—expanding flexibility for both ultra-fine and large-area imaging. The probe holder has increased the number of electrical contacts from three to ten. This enables measurements utilizing self-sensing cantilevers, thermally actuated cantilevers, Scanning Thermal Microscopy, device-on-probe, and more. The sample holder has increased the number of electrical contacts from four to ten. This enables samples with integrated complex devices, simultaneous SPM and transport measurements, scanning gate measurements, on-sample thermometry, and more. The PanScan Lumin option provides a highly versatile platform for the study of light/matter interactions. The integrated achromatic parabolic mirror allows over 70% of the emitted light from the far-IR to the deep-UV to be collected. The PSF II retains the PanScan Freedom's compact footprint and full compatibility with RHK's R10 Controller. Its unified cryostat design simplifies operation and ensures high uptime. For labs without magnetic field needs or limited space, the original Freedom remains available in 15 K, 8 K, and 5 K versions, all capable of world-class performance in real-world conditions. The PanScan Freedom II represents RHK's continued commitment to advancing the vision of nanoscience. Merging lower temperatures, magnetic versatility, and superior optical access, it delivers unmatched performance within a fully cryogen-free system. PSF II empowers researchers to explore deeper, faster, and farther into the frontiers of quantum and materials science.
