With the attoDRY800 optical cryostat the user receives a high quality optical table of his choice, which has an integrated cold plate of 75 mm in diameter. The cryostat is an integral part of the table, and comes in a standard configuration. The position of this cold plate can be chosen upon order. The vacuum shroud can have an almost arbitrary shape depending on the experimental needs of each user. We distinguish between standard configurations, which cover the most typical applications, and fully customized configurations.
From more than 25 years working at the forefront of cryogenic optics applications, as well as learning from our users, and anticipating typical configurations, we have designed several standard vacuum shrouds and cold shields, that are intended for certain types of positioners, sample holders, working distances and objectives.
These options constitute an economic pre-configured set of components that give the user a head start for the research with optics at low and variable temperatures. Most of our standard shrouds feature clever extensions by default, such as a feedthrough ring for optional additional DC, SMA and fiber feedthroughs, as well as a 30 mm and 60 mm cage system with quick release adapters centered around the top window.
Anything above the table surface can be customized according to the technical requirements and preferences of the user and his/her application. In the following, we show a collection of previously sold customized vacuum shroud configurations for the attoDRY800 optical cryostat. Alternatively, we assist customers in designing their own specialized low temperature setup and corresponding vacuum shroud.
Please note that in such cases, certain specifications can only be estimated. attocube will be happy to help with years of experience regarding special requirements in cryogenic environments. Customized shrouds and setups have a slightly longer delivery time compared to standard versions. Please do not hesitate to contact us if you have special requests.
