CryoSpectra brings compact cryogenic cooling to the UK

CryoSpectra is a class-leader in the production of superior very low vibration high-power cryorefrigerators that deliver 90 to 170 Kelvin temperatures into a vacuum chamber. High power laser crystal cooling, to guarantee Carrier Envelope Phase (CEP) stabilisation of femtosecond or shorter pulses, is just one application. Elliot Scientific is now distributing their product range throughout the UK and Ireland.

CryoSpectra_CatLogoSQ500Applications

  • Laser crystal cooling
  • High power laser amplifiers
  • CEP stabilised laser systems
  • Ti:Sapphire multi-millijoule, multi-kHz amplifier systems
  • Quantum Cascade Lasers
  • Cryopumping

With a high cooling capacity from a very small gold-plated cold head, CryoSpectra products are also ideal for use in a broad range of other demanding cryo-applications in industry and science – especially physics, chemistry and biotechnology, and the company can offer customised solutions too.

Features

  • High cooling capacity at cryogenic temperatures
  • Cool-down time 20 minutes
  • Compact cold head is vibration-free
  • Quiet and maintenance-free

Lake Shore Model 350 Ultra-low Cryogenic Temperature Controller now available

Lake Shore announced their new ultra-low cryogenic temperature controller – the Model 350 – back in February, but now the physics community can actually start to receive their orders as the first models roll off the production line in Westerville. The Model 350 is designed for the demands of pumped He-3 refrigerators, adiabatic demagnetization refrigerators (ADRs) and a number of other dilution refrigerators, providing excellent measurement performance, superior control accuracy, and convenient operation for a wide range of advanced research applications.

Patented noise reduction input circuitry is just one reason why this controller works so well for ultra-low temperature (ULT) applications, all the way down to 100 mK. When combined with precision Cernox sensors, this performance-optimised design allows as little as 10 nA of excitation current to be used, minimising self-heating effects, and ensures best possible measurement accuracy throughout the entire temperature range. The instrument offers extraordinary capability and flexibility, often eliminating the need for additional instrumentation in a refrigeration control system. Its four input channels and four independent control outputs are configurable to support a broad range of I/O requirements, including the heaters and auxiliary devices typical of ULT refrigeration systems, as well as other cryogenic sensor types like ruthenium oxide and platinum RTDs.

For more information and pricing of this and other equipment in the Lake Shore range, please contact us.
