ATTODRY700
cryogen-free table top cryostats with optical access
:.........................................................................................
This new pulse tube cooler system is optimized for optical (confocal) microscopy. An integrated anti-vibration system facilitates highly sensitive measurements in a cryogen-free environment. Together with a custom-made radiation shield, the outer vacuum casing and an exchangeable optical window, an easy integration into existing optical setups is enabled. As an additional benefit, the slim table-top system can be mounted onto any size of optical table.
Further features such as easy sample exchange, fast cool-down and turn-around times, as well as simple operation guarantee reliable operation and efficient experiments.
