The SHI-4 and SHI-5 are among the most versatile systems available for laboratory sample cooling. They are equipped with interchangeable optics, and include provisions for a wide variety of electrical connectors. Tapped holes on the vacuum shroud and a sturdy mounting flange provide for convenient mounting in any rientation.

These cryostats are designed for measurements to 325K, and optional configurations permit operation to 475 K or 700 K (with special thermometry).

Optimized for experiments requiring optical access to the sample, these systems include the following components:

• Optical vacuum shroud and radiation shield
• Four o-ring sealed quartz window
• Gold-plated OFHC copper sample holder
• 10-pin electrical feedthrough, with three spare electrical access ports
• Evacution valve and safety pressure relief valve
• Silicon diode thermometer and control hearter

• Additional electrical feedthroughs (BNC, SMA, multipin, and others)
• Rotatable vacuum shroud
• Matrix isolation configuration
• Fifth window port
• Radiation shield windows
• IR and other window materials
• Custom designed vacuum shroud
• 475 K & 700 K high temperature systems (700 K with special thermometry)
• Non-optical configurations
• Compact vacuum shroud (for use with electromagnets)
• Large sample volume configurations
