Microscopy Cryostats

 

This continuous flow cryostat was specially designed for use in microscopy, imaging and high special resolution photoluminescence. Ultra-low vibration and drift levels are achieved by combining a low thermal-expansion support structure with internal vibration isolation. The cryostat geometry allows a short working distance (for use with high magnification optics). It can be mounted on common microscope stages and translators.

This cryostat is portable, easily mounted in a variety of configurations and can be used both in transmission and reflection applications.

The system includes a flexible high efficiency variable flow transfer line which delivers liquid helium or liquid nitrogen to a two-stage heat exchanger and sample mount.
