here are currently two options available depending on your experimental needs

The Optistat™Dry comes complete with its own built-in diagnostic wiring, heater and sensor, which are wired to a 15 way micro D-type connector mounted on the room temperature connector flange of the cryostat.

Sample holder options  

Standard sample holder for optical measurements

These sample holders are ideal for optical measurements with no or limited electrical measurement requirements. They are made from nickel plated copper. The DRYRSH is best suited to reflection measurements. It provides a flat surface 30 mm x 30 mm to mount your sample. The DRYTSH is best suited to reflection measurements. It provides a 15 mm clear diameter hole and a clamp plate to secure your sample.

Wiring Options:

Experimental wiring can also be chosen as an option with the standard sample holders. This consists of a 21 way micro D-type connector mounted on the room temperature connector flange of the cryostat, wired in twisted pairs with 20 wires (18 constantan and 2 copper) to a cold electrical connector mounted just above the sample holder position. Mating connectors for the cold and room temperature connectors are provided as standard.

Puck-style sample holder for opto-electrical measurements (patent pending)

The sample puck provides 12 DC connections near the sample. The design has been optimised to give reliable electrical connections for your experiments and excellent thermal anchoring with the minimum number of thermal interfaces. These features result in a superior solution compared to leadless chip carrier and PLCC sockets.

The puck sample holder consists of a 21 way micro D-type connector hermetically sealed into the room temperature connector flange of the cryostat. This is wired with 6 twisted pairs (10 constantan and 2 copper wires) to a copper blade, which incorporates sprung loaded probe pins designed for DC applications.

The pucks themselves are made from a copper laminated PCB composite. When fitted to the sample holder and the screws tightened, electrical and thermal connections are made.

Wiring:

The puck style sample holders (DRYPUCK12R and DRYPUCK12T) are made from a ceramic filled PTFE composite, laminated with 35 µm thick copper on both sides. The copper has an ‘ENIG’ surface finish which is an electroless nickel layer, capped with a thin layer of immersion gold. It is a suitable for soldering and aluminium wire bonding. The gold surface acts as a good thermal contact and protects the underlying nickel from oxidation/passivation.
