MadMotor – a UHV-compatible piezo-driven micropositioning system from Mad City Labs
The MadMotor™-UHV is a piezo motor driven micropositioning system offering high precision alignment over long travel ranges under ultra high vacuum (UHV) conditions.
Mad City Labs‘ experience in manufacturing equipment for use in UHV ensures that the MadMotor™-UHV is vacuum compatible to 1 x 10-11 mbar and can withstand extensive periods of baking at up to 150 °C.
The rigorous requirements of UHV operation have ensured careful design of the MadMotor™-UHV stages by the Mad City Labs engineering team to deliver robust and reliable operation within your application.
MadMotor™-UHV stages can travel up to 10 mm per axis with high resolution and excellent repeatability, while optional eddy current sensors can provide 500 nm of sensitivity over the entire travel range. A complete system is supplied as a 1, 2 or 3-axis piezo motor driven stage and Mad-Drive™ controller.
CryoSpectra lowers the temperature with new K90 cryorefrigerator system
CryoSpectra deliver the simplest way to bring cryogenic temperatures into a vacuum chamber through their uniquely designed cryorefrigeration systems utilising gold-plated and polished cold heads of 38 or 50 mm diameter with CFF or KF flanges. Now available with base temperatures from 75 Kelvin , these high cooling capacity systems are easily the best way to cryogenically cool laser crystals.
The CryoSpectra K Series of low acoustic noise cryorefrigerators are especially designed for work in the lab. The closed-loop cooling system ensures maintenance-free operation, while the super-compact cold head guarantees an ultra-low vibration (0.5 nm peak to peak – see vibration data here) chilled surface for inside the vacuum chambers of high power laser systems.

Elliot|Martock waveguide holders now with ‘in copper’ option
Elliot|Martock waveguide/device holders are now available manufactured from copper as a special order at additional cost. Any of the following MDE74x range can be supplied as such for applications requiring a heatsink capability.
- MDE741 – Basic, plain mount for tape or adhesive clamping
- MDE742 – Vacuum clamping
- MDE743 – Mechanical clamping
The new holders are mainly for use with Elliot Gold™ series flexure stages and the central workstations MDE881 and MDE883, but can also be mounted on the MDE147, MDE148 and MDE149 brackets. The MDE744, MDE745, and MDE746 models are special versions of the MDE741 to MDE743 models for use with the MDE717 and MDE718 fibre rotators.

Photonex Visitors Focus On Elliot Scientific
Elliot Scientific’s exhibition team were pleased to meet a variety of visitors from the UK and abroad over the past two days at Photonex – the UK’s premier exhibition and conference on all things related to light and optics. Held at the Ricoh Arena, inside Coventry City’s football ground, the hall was filled with leading figures from research and industry, and the best technologies the UK has to offer in the fields of photonics, machine vision and vacuum.
We would like to thank all the people who came to Stand B10 to discuss how Elliot Scientific could aid their application or research project, see our equipment demonstrations, or who just stopped by for a chat. We hope we have helped you in some way and look forward to seeing you again next year.
The 21st Photonex will return in October 2012 at the same venue.
New hybrid low temperature system from Janis Research
Janis Research Company has developed a new hybrid low temperature system. The versatile model 2K-VTI variable temperature cryogen-free (dry) system has been combined with a wet (LHe cooled) 9T/4T vector magnet to provide a system that offers low temperature and high magnetic field measurements.
The 2K-VTI can be integrated with either wet or dry magnets, and can be configured for sample in vacuum, sample in ultra high vacuum (UHV), sample in exchange gas or even sample in liquid.
The 2K-VTI cryostat can be operated in several different modes, allowing the user to optimise the cooling method for the particular sample and experimental requirement.
