ST-500-UC ultra-compact optical cryostat
The Lake Shore ST-500-UC continuous flow cryostat has a very low profile (1.163 in) and has been specifically designed for use in microscopy and imaging applications. The combination of the low thermal-expansion support structure and internal vibration isolation results in low vibration and drift levels. The cryostat geometry offers a short working distance (for use with high magnification optics) between the top window and the sample.
Standard configuration
The ST-500-UC system includes a flexible high-efficiency variable flow cryogen transfer line. This line delivers liquid helium or liquid nitrogen to the heat exchanger and sample mount. The ST-500-UC is portable, easily mounted in a variety of configurations, and can be used both in transmission and reflection geometries.
Options include:
- A variety of window materials and sizes
- Interchangeable sample mounts for different sample thicknesses
- Electrical feedthroughs
- A complete system solution including temperature controllers, pumping systems, and storage Dewars
- Looking for a cryogen-free option for your existing ST-500-UC? Optional recirculating gas cooler eliminates the use of liquid helium for "wet" systems.
