規格說明 / Specification：

 

Our closed cycle optical cryostat temperatures down to 1.5 K without the need for liquid helium.  Low base temperature and easy to use.

 

It is the cryostat of choice for applications such as detector cooling requiring low vibration, a low base temperature and a large sample space.

 

• Wide temperature range from 1.5  to 300K

• 4 K base temperature models are also available

• Versatile with sample environment available as vacuum or exchange gas

• Top-loading and bottom-loading systems available

•  Fast cool down time: cool down to 1.5 K in less than 6 hours

•  Low vibration using a Pulse Tube Refrigerator.  The rotary valve in the cold head directs the helium gas in and out the expansion tubes dropping the temperature to 2.8 K without the use of displacers

• Electrical measurements via 10-pin electrical feed wire to heat exchanger and/or wired on coax connectors
