SK300

Optical & Closed-Cycle Cryostats by Four9 Design (US)

Overview

The SideKick is a helium-free, compact, ultra-low-vibration cryostat that delivers true sub-4 K performance without crowding your optical table. By relocating the cryocooler and pumps to the lab floor, the SideKick keeps your experimental area clean, quiet, and accessible from every side. Its cryogenic sample space mounts directly to your table like a standard optical element, while the remote architecture provides exceptional vibration isolation. Built exclusively from low-outgassing materials and featuring a differential vacuum-seal design, the system routinely achieves ultra-high-vacuum performance without the hassle and cost associated with traditional UHV systems. With industry-leading cooling power, the SideKick supports rapid thermal cycling and fast cooldown times, enabling high-throughput device testing and accelerated iteration. Automated cooldown, warmup, and system control—along with fully remote operation—further streamline workflows and allow unattended runs or integration into automated test environments. Combining superior cooling power, vibration isolation, and vacuum performance, the SideKick is one of the most configurable cryostats available. Its flexibility makes it ideal for advanced quantum applications, including trapped-ion experiments, photonics and integrated quantum optics, and superconducting device development. Supportable options include: DC and RF wiring, fiber-optic interfaces, superconducting magnets, <1 K stages, cryogenic and in-vacuum objectives, low-working-distance free-space optical interfaces, nanopositioners, photonic probe-station configurations, variable-temperature stages, and more.
