規格說明 / Specification：
Our closed cycle optical cryostat is a sample in vacuum cryogen-free 4 K cryostat, no liquid helium required and easy to use.
The cryostat is capable of achieving sample temperatures as low as 2.8 K without the need for liquid helium. This brings significant benefits in terms of running cost and ease of use.
Low running costs
Wide temperature range 2.8 K - 325 K
Two models to choose from depending on your cooling power requirements
Easy sample change
Low vibration using a Pulse Tube Refrigerator (PTR). Typical displacement amplitudes on the second stage heat exchanger in the radial and axial directions are typically 7 and 12 micrometers respectively
Large sample space, with a sample in vacuum environment, enabling studies of samples with a wide range of size and geometry
Optimised clear beam throughput (12.7 mm diameter aperture) allows a large illumination area for measurements involving the detection of low intensity light
Electrical measurements via 10-pin electrical feed wire to heat exchanger
